Your video card is nice, but you could go with something like a i7 and 6 ~ 8gb of DDR3 and a SSD.

ohhhhh.....i see!!!!!......so that is my current cpu which is incapable and bottlenecking my card,,,,,by the way tomm is my week off.,...i will go to the market and buy new 800watts psu...and check first.

Phenom-2 x6 1100t would be kickass. It would be able to push two 5770 cards in crossfire. Your current CPU is nice, but their might be a problem with your current rig. Get that new power supply and test your current rig first.

okay....let me try that first then..

This is my AMD system, GPU is ATI 5770, 4gb of corsair xms DDR3, MB is Asus M4A88TD-V EVO/USB3, I can play all my games maxed out 1920x1080 the only 1 I still have problems with is Crysis (get less than 20fps)

thanks for your comment...but i have already decided i will upgrade from athlon2 635 to either with phenom2-x6 1090t or phenom-2 x4 970

and would switch to ddr-3 memory as well.
