I have a AM2+ 9750 quad 95w with a foxconn AX78S. Just upgraded from an AM2 duel core wich only took ddr2 800 memory. I just got an ATI 4890 and was wondering if I should upgrade the ram to DDR2 1066 and if I would see any preformance upgrades. Any info you can give me would be a great help, thank you.
