I was using 512 MB RAM, and even putting a 256 MB RAM next to it improved load times everywhere. Windows stars much quicker, also programs like Photoshop, vegas, and games also of course ( far cry, doom 3 etc.) . IMHO 1,5 gigs of ram is enough, but i would not mind 2 gigs of it

. BUT You can't really use the lots of ram without other "high end" components ( 3+ GHz cpu, good graphics card -anything better than a 6600 GT or equivalent ati card - ), mainly because new games are huge, so they need loads of ram to load and run quickly (and to run quickly they also need the other parts described above ) . It's all just my opinion, so pls don't flame me
