I would get at least 512MB more, might as well get a 1GB stick. Just with Vista on there, I've heard it really eats the RAM. Are you using the vista crack that you posted... Does it work?
havent tried it yet, im waiting on my raptor, it comes tomorrow. Ill probably end up buying vista, because i have a feeling Halo 2 is gonna need genuine windows.
hell with it, I'm just gonna buy Home Premium, there really not all that different... If I'm unhappy I'm pick up Ultimate down the raod when it's cheaper... http://www.microsoft.com/windows/products/windowsvista/editions/choose.mspx
