With the two newest games in our benchmarking line-up, there were a few problems. The XXX seemed to be scaling down it performance at the lowest possible settings for X3. X3 also happens to be the game the ATI X1950 XTX performs the best in.
With Company of Heroes, we decided not to include scores with AA/AF off. We are currently reviewing our benchmarking scheme and are likely to change it to include higher resolution testing with AA/AF on. But for now, these scores clearly indicate that the extra stream processors the GTX has over the GTS are extremely beneficial.
