hi, happy new year all, want to ask question
just upgraded my xp to vista, now i feel that my ram nto enough
my rig q6600, zotac 8800gt amp, 2x1gb ballistix tracer, 560w true power.
planning to buy new 4gb kit ballistix tracer ,can i add 2x2gb in?? would it affect my oclocking performance? 6gb total, can i have 2gb kit + 4gb kit in my rig? or should i sell off my old 2gb kit and get 4gb kit + 4gb kit ???

i upgraded to vista ultimate 64 bit, so can use ah?? mmm okay cool thanks man, how bout overclocking wise?? performance will be the same ah?
