4gb Ram is now becoming the low end of the scale, and you're probably going to need 8-12gb soon to run games like Battlefield 3 and MW3.
RAM has very little to do with running games, so I don't know what your on about. The only reason you would need more then say.. 3-4GB RAM is if you have 100 unnecessary programs running. I'm running off of 2GB RAM and I can have chrome open, itunes playing, sc2 open, msn, and a whole lot of other junk and I don't even surpass my memory capacity. I mean, maybe its 'cus I learnt to be efficient - I've been gaming on a 1GB RAM comp for a few years before upgrading to 2GB.
