I really hope that this falls into the better late than never category. The HD 5450 and HD 5570 were launched earlier this month and like some sort of immortal demon for whom time has no meaning, I just finished adding them to the site. These graphics cards are cheap DirectX 11 cards for your HTPC or workstation which are a return to GDDR3 and DDR2 memory for ATI.
I have been able to find the names of the graphics chip(s) that the HD 5670, 5570 and 5450 are using so for now I have tweaked the RV850 chip for each of these cards so that the fill rate and operation numbers all come out to match the advertised speeds. If any of you can find the chip names for these cards, please let me know.
I receieved a free copy of Dark Void from Nvidia (thanks Nvidia!) for the PC because it supports 3D Vision and PhysX but it turns out that it is a really bad game that is not fun at all. I was completely unable to shoot any UFOs during the opening of the game (which by the way is the worst opening for a game ever) even after tinkering with the controls for a long time. They should have called the game Dark Avoid, because you should avoid it.
