Far Cry 2
FarCry 2 Ultra settings and a resolution at 1920x1200 don't mean a thing to the new Sapphire HD 5970 OC, and it beats the GTX 295 by about 20%. Interestingly enough, it runs only slightly better than the one year old 4870 X2.
After turning on 4X antialiasing at 1920x1200, the situation changes somewhat. Sapphire HD 5970 OC still tops the chart and beats the GTX 295 by 20% with ease. Radeon HD 4870 X2's performance however drops significantly and runs by about 40% slower than the HD 5970 OC. The single-GPU HD 5870 is only slightly slower than the HD 4870 X2, and more than 45% slower than Sapphire HD 5970 OC 2GB card.
We see "similar" performance difference at 2560x1600 without AA and Sapphire HD 5970 OC runs about 25% faster than the GTX 295. The HD 4870 X2 runs slightly slower than the GTX 295. Just for comparison's sake, the HD 5970 OC is four times faster than Geforce 9800GT and almost four times faster than the HD 4850.
Sapphire HD 5970 OC churns out 70fps in FarCry 2 at 2560x1600 and 4xAA, which is more than enough for smooth gaming. The GTX 295 scores 57fps, which is about 20% slower. This proves that Sapphire's HD 5970 OC card is more than enough to chew up anything you throw at it and spit out a so far unprecedented fps count.
Left 4 Dead
