Most of my games are not limited by my cpu nor my gpu. Usage for both doesn't go over 75% but frame rates are still low. Im thinking it could be my ram but don't know for sure. Heres my specs: XP pro sp2 + Vista ultimate 32bit intel board P4 3GHz HT 1.5 PC3200 3850 AGP 512Mb 430W Antec Dual 12v 4 HDD's: 1 Sata, 3 Pata All 7200rpm Im planning on getting a pair of 1Gb sticks soon. What do you guys think it is?
