nice mobo... P5Q pro.. might i suggest nga gigabyte EP45-UD3L becuase of the 24 pin location man gud
now back to topic....
for you video card ... that depends on what type of games you play.
if you are the First-Person-Shooter type.... suggest ko ug 9800GT series nga vidoe cards... or the GTS 250..
pwede sad HD4850 and the HD4770.
kung online gaming ra imu like RAN, WOW, Perfect world, and RF online... same gihapon sa taas.

dinha lang akong ma tubag..... btw... pila imung budget sa video card... if dako... diretso dayun GTX series sa NVdia
