I am currently running an AMD Athlon 64 X2 Dual Core Processor 4800+ 2.50 GHz and NVIDIA GeForce 8600 GT 512 MB Graphics on the Acer Manufactured F690GVM Motherboard. I want to know which of those two I should upgrade first, the processor or the graphics, to get the best out of modern games. Also if anyone have any suggestions on what to upgrade to from what I have that would be greatly appreciated as well. Thanks
