i get lag in games i should not(cod5 and cod4, gta 4, crysis and farcry 2). i know i should be able to see no lag in cod 4 on high settings but i do at medium and high and highest. i cant play cryis on high without major lag. farcry2 2 jumps continuosly and i was wondering what the problem was between ram the processor and the gpu.

i play at 1280x1240 and run xp 64bit
