I just wanted to update this thread to thank those that helped me and to inform others that might be having the same problem. It was definantley the CPU keeping the 4890 held back. I bought a brand new AMD Athlon II x3 435 and OC'ed it to 3.23GHz and now I get about 41 FPS in Crysis Warhead opposed to the earlier 33. Thanks again!
hey I also have the same problem .....Does your motherboard support AM3 processors?
