I built my girlfriend a low - mid range gaming pc and the ram seems to be the bottleneck because the original plan for the 6gb DDR3 got ruined because of a incompatible ram module so i just have a single Samsung DDR3 1333 2GBx1 and i was looking to change to Wintec Ampx DDR2 800 1GBx2 module. Is there going to be any noticable performance difference between the two?
