      You have to understand that the HD6450 is not a gaming GPU in the first place, it's the absolute lowest of the low in the Caicos line. Also, Michael is probably using the DDR3 HD6450 instead of the GDDR5 version.

      I'm using an HD6450 (DDR3 version) which doesn't work with open source drivers, but works pretty good with latest Catalyst beta.

        What's with every r600 card regressing? Is nobody using those anymore and reporting bugs?

            Is that what you are considering buying? I'm looking at those, too, but also the 6770 and 6850. Would you or anyone else recommend any of those cards?

            It still is unbelievable to me that the 7xxx cards are still not functional enough. I prefer a single slot card or at least, not one of the oversized cards (see 6870). It won't fit in my case, unfortunately.

            The problem, too, is that the 6770 cards are still expensive and 6850, one has to buy used.

              As mentioned by a earlier poster, the patches for making the 7000 series work are already in place. You just have to have LLVM 3.4.

                Yes but I havenít been able to find benchmarks for the 6670 or the 7750, and I have read that Metro: Last Light doesnít work properly with the open-source drivers yet anyway. I think that M:LL needs GLSL 1.50.

                My case will only accept a single-slot low-profile card; I donít know if the 6770 and 6850 are available in that size. Iíd also like a card that consumes less than 10W when idle and doesnít make much noise.

                  Speaking of TF2 performance with r600g, it seems like I'm always locked to 60fps, no matter what I do. I have tried using driconf, turning vsync off in TF2 and even launching Steam/TF2 with vblank_mode=0 to no avail. Any ideas?

                    Set SwapbuffersWait off in your xorg.conf.

                    example:
                    Code:
                    Section "Device"
                        Identifier "Radeon"
                        Driver "radeon"
                        Option "SwapbuffersWait" "off"
                    EndSection

                      I don't get you guys that want an impossibility: Silent, Single Slot and Performance. Just go with a midrange card with a dual slot cooler, it'll run much quieter and will increase your case ventilation instead of dumping all of it's heat into the case increasing the temperature of everything else.

                      The midrange HIS IceQ cooler equipped models are about as quiet as you're going to get without going with the after market coolers for the high end cards that fit 3x 80-120mm fans.

                        Damn 1 min edit limit...

                        Theres no point in getting the *450 series, the top end APU GPUs are much faster, they exist only for those that need to add an extra monitor or have bought a system with no onboard GPU and don't care at all about performance.

                        If you require a small system with a half decent GPU for whatever reason then just get an ITX system built around the A10-6800K or i5 4570R for Radeon HD8670D or Iris Pro 5200 goodness with the option to add a PCIe GPU later.

                          This is exactly what I did, but 3 years ago with a 1st gen Core i3. I hadnít anticipated that almost all graphics cards would require 2 slots and my case only has room for one. It might be a good moment to replace my Antec ISK310-150 with something slightly bigger, less noisy and with room for a proper PSU and graphic card thoughÖ
