since you're going with 32-bit vista, 2gb of ram should be enough even for most demanding games.<br />on the other side, 8600gt is a total waste and won't help you much (if at all) with gaming. if possible, change that card for 8800 gts 320mb.<br />instead of ocz's 850w gamexstream, go with pc power and cooling 750w silencer.<br /><br />and finally, 4 cores will not help you in games so unless you plan to do heavy 3ds max modeling, you'll be better off with e6850.<br /><br />in order to get additional money for 8800 gts 320mb, you could try getting cheaper mb (chek out our mb reviews
here, going with 2gb of memory and buying single 500gb drive unless raid is what you really want).<br /><br />
