I have a AMD phenom ii 1100t black edition 6 core cpu, 8GB of of g.skill 1333 DDR3 ram, XFX 7950 ati video card. Not sure what other info would need. But I am trying to figure out if I should upgrade entire system or upgrade parts on current computer? I was thinking of getting another 7950 and crossfire them, but if it won't help that much I won't. Thanks
