  • Questions regarding gaming hardware

    Hi,

    I am going to buy a new desktop computer. The two main usages for the computer will be gaming and computer virtualization, gaming for leisure and virtualization for work. I title the thread for gaming because if the setup gives enough cpu-power for games it should feed my virt. needs. RAM i will have.

    First i was thinking of an Intel based cpu, but iam interested in running 64-bit linux. Though iam not sure if an amd64 gentoo system will support all the applications i want to run, and no packages in portage seem to support ia64. AMD/ATI is also doing a lot of nice moves toward openness. Therefore i think i will go for an AMD/ATI Phenom.
    Any input from you on AMD/ATI vs. Intel when it comes to 64-bit support on linux? Sure Intel have more power, but Phenom seems enough for me and i start to really like AMD/ATI. There is a lot of talk about future Phenom processors, will they use the same socket (AM2+)?

    If i run an AMD/ATI processor i would like to run an ATI based card. I have been looking at Asus Extreme HD3870 512MB GDDR4. The Nvidia card i have been interested in is: Asus Extreme GeForce 8800GT 1024 MB. Any opinions about those cards running under linux? What about their performance today and in the future?
    I have read reviews and tests about both cards and i find them quite equal. I am mostly playing Team Fortress 2, but i would like to be able to play future games too. But iam not gfx junkie ;-)

    Does anyone have any good/bad experiences about any ASUS motherboards? I have been looking for reviews at phoronix and found one, but user experiences are always nice! If i go for AMD i will most likely go for: Asus M3A32-MVP Deluxe.

    What do you think about crossfire and/or SLI under linux in the future? How is the support today?

    Answers on any question above is appreciated!

    cheers,
    frej

    Though the arch is named amd64 does not mean that intel is not using basically the same. That is all the x86 compatible intel CPUs (like the Core2 series) are based using amd64 (as it is named in gentoo) as 64bit arch. Another common name for the arch both AMD and Intel use is x86_64. Still both are basically (binary) compatible as long as you don't use explicit cpu specific optimisations.

    On the other hand ia64 is Intels (not so well known) server architecture Itanium. It has some really nice concepts, but it *not* meant for Desktop systems at all.

    If i run an AMD/ATI processor i would like to run an ATI based card. I have been looking at Asus Extreme HD3870 512MB GDDR4. The Nvidia card i have been interested in is: Asus Extreme GeForce 8800GT 1024 MB. Any opinions about those cards running under linux? What about their performance today and in the future?

    I got a HD3850 512MB in my system (Gentoo x86 unstable based) and it works really well. No problems with fglrx or anything. I can play etqw in 1920x1200 with high details and the game is 100% fluid. It even is CPU limited, not graphics limited... I bought the card simply to have something for (future?) games (yes, I am a Linux only user!) and to support AMD/ATI for their approach to open specs.

    What do you think about crossfire and/or SLI under linux in the future? How is the support today?
    Today there is only SLI support in linux. But reading some of Michaels post I got the impression that Crossfire might come in the nearer future, too. But in general I don't think that these techniques are (currently)not of too much use since you don't double (not even nearly) performance when using two cards. You only get something like 60% more performance. Maybe in the future when the design of graphics cards goes more in the direction of "many simple chips on one card and the driver organizes what happens" this might change, but ATM it is probably easier to just buy one card and later on, when this card is too slow, sell the old one and buy a new.

    The only area where "more cards are better" is *really* valid is in "stream computing" using the graphics cards to do work with the various stream SDKs.

    Does anyone have any good/bad experiences about any ASUS motherboards? I have been looking for reviews at phoronix and found one, but user experiences are always nice! If i go for AMD i will most likely go for: Asus M3A32-MVP Deluxe.
    Hmm, I have no own experience with those board (since I am currently running and Intel based system). But IIRC Asus is basically "reference class" when it comes to AMD based systems. Though I think their reputation is not this good for Intel based systems, there it is more Gigabyte who is in the lead.


    Overall: I think when building a complete system today I would go for a phenom based system with an ATI graphics card since there I would get most for my (not too many...) bucks.

      ivanovic thank you for your clarification regarding the arch question. I guess Intel quad core cpu's work with amd64? Do you know anything about driver support and such on amd64? Is it possible to compile 32 bit source, for any kind of software, and run on amd64? The main reason is because i would like use more than 4G ram, i know it is possible on 32bit with HIGHMEM but i would prefer to run on all 64bits. Because the cpu will also get a boost.

      Nice to hear that you are happy with your graphics card.

      Yes Phenom seems to be good power for the money. If i recall correctly we will see more powerfull cpus coming in the phenom series. I assume they will run on the AM2+ socket. Then you can get some extra power in the future without buying new mobo. But Intel Quad is quite much more powerfull according to the benchs i have seen.

        One of mine is a Core 2 Duo E2160, and I run it fully 64-bit.
        64-bit kernels can run 32-bit apps, you just need all the 32-bit libs too. So double HD usage, but still, extra 5G shouldn't push current Hd's in any way.

        For driver support, I assume you mean chip-specific stuff? If so, I can read the cpu temperature using lm-sensors and the coretemp module. All drivers run fine 64-bit, that system is actually having a PCI Ati Rage II+dvd running fine, with 64-bit drivers.

          Intel's quadcore processor are not really that much faster, and the newer 45nm CPUs of Intel are way too expensive. I'd go with the ASUS board you've mentioned, if you can't wait. Otherwise, I'd go with one of the upcoming boards that have got the new SB750 southbridge, may it be Gigabyte or ASUS. A Phenom X4 and Radeon HD 38xx on top of it and here you go.

            If you go with the nvidia card don't bother with the 1024mb RAM version apparently it offers no benefits over the 512MB version.

            If you don't need the hardware ASAP you might like to wait till the end of July as nvidia and ATI's new graphic's cards are meant to be out then meaning you can either get a better card of enjoy the price drops on the current gen ones.

              Thank you all for your repsonses! I Think i have got the answers i need.

              I have been thinking of waiting a bit with my purchase because i have read indications about new hardware from AMD/ATI. But unfortunatly i think i want to buy asap ;-)

              It is fun to read about your experiences. Because i have not been using linux on my desktop for a couple of years. I have not had a proper desktop at all actually. So it is fun to read about your good experiences with hardware and linux today. When you only work on the server side you loose the focus on the desktop side.

              Will post a reply when i have done my purchase,
              cheers

                Some users have reported problems with 64-bit OS and our drivers, which seem to be related to SBIOS remapping above 4GB. At least one of the ASUS motherboards didn't seem to be able to turn remapping off; does anyone remember if that was a mobo for Intel or AMD CPU ?

                  The option is present on the Asus M3N-HT Deluxe and IIRC as well with the M3N-HD HDMI IIRC.

                    Hi,

                    Just one final question before i purchase. I am quite into green things, some people laugh and some people cheer. I like to make decisions that is environmentally friendly. Many manufacturers have start to make green products and i would like to encourage that.

                    Therefore i would like to know if anyone know if ASUS has any green mobo, like the Gigabyte one reviewed on Phoronix.com (http://www.phoronix.com/scan.php?pag...es_green&num=1)

                    Currently iam into this PSU "be quiet! Dark Power Pro First Class 450W". But i do not know if it is really green, but it is stable and low watt. At least compared to what my friends put in their machines.

                    Frej

                      I don't know of any ASUS "green" motherboards but there may be some out there. For the PSU go for one that is 80 PLUS certified and you'll have a fairly green PSU.

                        Thank you! The one iam going for is 80 PLUS Cert. http://www.be-quiet.net/be-quiet.net...php?StoryID=55

                        According to a review of different PSU's i read recently they claimed that 450-550W is sufficient for most desktops today. Do you think they are correct? As i mentioned before most people i know buy much stronger PSUs. Is 450W sufficient today? Which are the most demanding components?

                          Never heard of be-quiet but as long as there are good reviews from credible sites it should be fine. As for the power requirement 450W PSU will cover normal setups and only starts to fall short when you use an OC'd quad core with something like a 8800GTX or 9800GX2 so you should be fine.

                            Be-Quiet is a well known PSU producer over here in Germany. They are among the best (regarding quality and noise level). You should be really fine with the 450W version. In some gaming mag they were running a sli machine with two 7800GTX and an overclocked core 2 "don't know what" (might have been a quad). This setup was run with a good 350W PSU and working rock solid so you should be perfectly fine with the 450W version. Though the really cheap (and thus low quality) PSU made the machine basically die shortly after the start. But with BeQuiet you should be perfectly fine.

                              One problem with old PSU is always that you have too few connectors for new hardware. Like you miss the PCI-E connectors (now you even need 8 pin ones too) and when you have got lots of SATA drives then you need more power connectors. I even had to use an adapter for my SATA DVD burner, just because my 3 hds are too far away from it (big tower). I think they really should add more SATA connectors for current PSU (mine had only 2x2).
