I just upped my texture size to 1024 w/hires pack and using 4xAA at 1280x1024x32 and still get 75 FPS. Couldn't do that with the 7900GT I just had. I don't even get stutters either. Might be because i have 3 HD's, C:\ is a WD raptor, D:\ is my WD16 320gig Game drive and e:\ is another WD16 320gig as my Backup and Swap file drive. I think its the best setup u can have is 3 physical drives. This way it can access all 3 drives at sametime, C drive for window files, d drive for game files and e drive for swap files if needed.
