Hey guys,
I need some help. I am shopping for a new CPU. I was told to purchase the AMD 64 4000 for games, but I also was told to purchase the AMD X2 3800. I dont know what to go for? Will someone please let me know which is better for gaming. I purchase the Readon X800XL. I purchased it for $250. Should I return it and purchase the nDivia 6800GT? I will also need a motherboard. I would appreciate if some one can help me out.

Thanks.........
