Hey I was wondering say I have 1gig of ram how much is that really for a game that requires 1 gig of ram is there a way to tell how much you really have for games because I know vista hogs ram,,, is there a site like systemrequirementslab.com thats vista friendly because for example that site says I can run Doom 3 pretty well but in reality i cant because of the hogging of ram. Is there a way to know how much ram is really being hogged? thanks
