The only problem there is that only NVidia cards run the game at full quality...If you hvae the game and update it, in the readme it states:
So, whenever you hear about ATI outperforming here, it is either an uneducated or a biased statement. Surprisingly not many have noticed this.
Well, you could, but there's reall no point. The only instance where you would want to do that is with the right kind of 9500 np, where 4 of the pipelines are disabled, and can be enabled by the new BIOS...As it is, only clock speeds are different. And, as to the topic, it depends what kind of...
Only core and memory speeds, and while the 9800 can often easily be overclocked to pro speeds, I went with the 9800 pro as I have given up overclocking.
Most MB's have automatic timings...For instance, I am running 2700 on my 2400+ and the RAM runs at 333mhz with the fsb @ 266mhz. More than 1:1 is available, is what I'm saying.
