K as the title said I have a question of what way to go. I'm getting ready to put a little money into my pc, about $5-600. I'm gonna be helping a frein out by giving him what ever parts I upgrade. Both pc's are mainly for gameing. Main game right now is AoC. He has a old amd 3500+ with a ATI crossfire MB 939. I forgot what one but it has 2x PCI E 16x slots. And a X1800XT. Now I'm trying to figure out what he would benifit most from. A C2D E6600, he will buy a 650I mb, or a 8800gts 640. I was thinking that the E6600 would be best and I was gonna either get a Q6600 or a 8400 and a second 8800. But now Im reading that a GFX card would give him the better boost. So I'm a bit at a loss so I figured I would try to see what you all thought. And thanks for any suggestions.
