today for most games 512 mb is enough. 1gb is excellent and 2gb is basically unnecessary right now and a waste of money.
I heard before that if you add any more memory over 1gig it will not improve performance e.g. games. and that it is usually used for servers. would going from 1 gig to 2 gig make a difference in games like doom 3 hl2 bfv and rtcw:et?
