    Processor/MB help

    I'm looking for a new processor and mobo for my desktop to replace this craptastic Pentium D. I'm undecided whether I should go intel or amd. I guess really what I am looking for:

    -low heat output(the computer room is about 5 degrees warm than the rest of the apartment)

    -preferably under 200 for both a mobo and cpu

    I guess im mostly just wondering about the power/heat and what kind of processor to get

    Thanks!

    Try to get a used cpu, a new intel cpu is stupid to buy this year. I prefer usually E8400 over Q9300 because of the higher base speed. E3300 well is a celeron with small cache, not ideal, maybe for oc. Next year it will be the year of sandy bridge cpus until bulldozer comes out - much more expensive than your sample cpus but much more powerfull too.

    Can I bump this to ask a question on processors? If the OP wishes to switch the topic back, it's fine with me as I don't want to crap on the thread!

    I am just wondering if one had to stay with LGA 775 socket, which cpu would you get (for prices now).

    I have the option of new - E3300
    used - Q6600 - $100
    used - Q9400 - $150 (that's if I can get the seller down)

    I'm inclined to think the Q6600 is the only one worth the price but what do you think?

    I have parts for a 2nd machine and just need the cpu and maybe a video card. The mobo is an Asus P45. My current machine is also LGA 775 w/ a Q6600 cpu. I prefer to have the two machines more or less similar in power so I thought a Q6600 for $100 is a better deal, overall, than a E3300 for $50. Right?

    I would like to upgrade to a newer architecture, whether AMD or Intel, but I have all the compatible parts, RAM etc., so I thought it's cheaper to just get a cpu and voila, a 2nd machine!

    What do you recommend?

    Except for the 785G, which is actually an RS880 -- the same as the 880G, but clocked a little lower.

    AMD 870 board (no IGP, so it runs cooler). I prefer BIOSTAR, but there are similar boards from other manufacturers, so take your pick: http://www.newegg.com/Product/Produc...e=&srchInDesc=

    CPU: Phenom II X2 BE 555
    http://www.newegg.com/Product/Produc...82E16819103846
    Fast dual-core CPU for under $90, very possible to unlock extra cores if you want to.

    Be aware that the maximum power consumption is not necessarily the same as the amount of heat that a chip gives off, and is not necessarily comparable between different manufacturers.

    I would guess that ANY new AMD chip will make less heat than a pentium D. Right now at idle, my AMD 1090T is a whopping 18.5 deg C with a fairly large but very slow (silent) air cooler. That's a 125 watt chip. My previous, an X2-4800, also 125 watt, made LOTS more heat. I don't remember ever seeing it (heat soaked) run less than about 45 deg C -- and that's with the SAME cooler. Under full load, the X2 would run right up to 60 deg C (its limit) and back off to lower clocks. This 1090T won't go over 35 at full load.

    And before anybody says something about the sensors... the finger-test confirms it. Believe me, you can feel a 25 degree difference with your fingers easily. Its the difference between frozen ice and nice-and-warm. Or in this case, nice-and-warm and you-dont-really-want-to-touch-that.

    Also note that you can make a fast chip give off less heat by forcing it to slow down... i.e. the difference between an AMD 1055T at 95 watts and an AMD 1090T at 125 watts is 400 MHz and the associated difference in voltage.

    In other words, don't worry too much about the heat. Better to force it down, that way you can let it rip any time you want to. You should think more about how much heat it makes with respect to the work it does in making that heat.

    I know you say that you prefer the M/B+CPU to run you under $200, but you say it in a somewhat flexible manner.... if you don't mind upping it to... say... $300-ish, you should consider yourself an X6-1055T (the 95 watt version -- also available in 125 watt, so be sure to check) -- the chip should cost about $225, add in a 785G or 880G M/B for under $75, you're in at about $300 for the M/B + CPU.

    Well worth the difference.

    I would not get the i5-750, because i5-760 does not cost more - in case you want intel for sli enabled boards which is not possible with a current amd board and amd chipset (only with nv chipset). Maybe a X4-965 BE is the smarter choice for the money as USB3 would currently run faster on AMD series 8 boards. This is true until Intel series 6 boards will arrive.

    OK, your other parts sound pretty up-to-date.

    Otherwise, not much else I would add. I'm guessing a dual-core CPU would be enough for your needs. Program compilation does not benefit much from extra parallelization.

    If the $200 soft limit includes the price of RAM, then you could probably still make it work with AMD parts. I don't think that would be possible with Intel. I will stick with my initial suggestion of 4 GB RAM.

    Phenom II are better than Athlon II in having more cache and a few other details. Athlon II are cheaper. Note the 65W bin of the dual core Athlon IIs, since you mention concern about thermals.

    CPUs - AMD
    Dual core Athlon II X2 $51+ 65W
    Dual core Phenom II X2 $86+ 80W
    Triple core Athlon II X3 $75+ 95W
    Triple core Phenom II X3 $89 95W
    Quad core Athlon II X4 $89+ 95W

    CPUs - Intel
    Cheapest Socket 1156 is $100, rated 73 W.

    You don't need on-board graphics since you have a card, it doesn't sound like you're into overclocking, so your mobo requirements are not extreme. My personal preference has been for Gigabyte for the all solid-state capacitors, but I really don't have much experience with other brands for comparison.

    cheers,

    I do quite a bit of compiling and also I'm currently doing OpenGL programming.

    I just bought a New PSU, A new gfx card(HD 4670), the hdd I have is only 1 year old.

    No real need for usb 3.0, no need for dual pci-e, I have an extra firewire pci card lying around.

    So there's a bit more info
