High Quality AA and AF
Our high quality tests let us separate the men from the boys and the ladies from the girls. If the cards weren't struggling before they will start to now.
Turning on AA and AF we can see that the GX2 is able to leap ahead of the GTX offering almost a 50% gain in performance. The HD 3870 X2 runs about 35% faster while the 8800GT OC sits about 10% behind.
Half Life 2 (Episode Two HDR)
We again see the 9800 GTX fall behind a fair bit. The HD 3870 X2 continues to give a good boost in performance while we still see a decent jump ahead of the 8800GT OC.
World In Conflict
Moving to WIC we can see that again in the minimum department the dual GPU cards and the 9800 GTX perform quite close together, when you look at the averages though the GX2 manages to pull ahead by about 20%.
