that is, if you think you know how, listen, its not your cpu or your video card, anandtech and everyone else in the forums can prove that to you, and like your previous thread that the x1900xtx "sucks" and everyone flamed you because you didnt know what you were doing, and got banned from another forum proves you werent listening to anyone. i have one question, have you upgraded your psu and if you have, how many watts is it, and whats the amperage to your video card, because from that thread you've had the same problem. i dont, i have a 17a seasonic, and it gives up to 19a, i have NO stuttering and NO slowdown unless its because im overwhelming my computer in a whole. oh and not to mention, that my cpu isnt all that much faster than yours too. so i would be having the same problem if my cpu is a bottleneck. so obviously its not your cpu. and like i asked, if your temps are getting wayyyy outta hand, then maybe its cuz of that....though its unlikely.
