That cant be true, lots of budget gaming PCs use a high mhz (dual channel if they can spare the money) 4gb RAM setup

Read my post carefully, i've told that when 32-bit OS limits your ram to 3.25GB, you are not able to play on V2D due to lack of RAM, that means, it's using somewhere around 4GB of RAM (of course together with some applications). Another thing, his RAM might be corrupted, anything else might be too, running memtest86+ won't hurt though. And as i said, check your most important drivers, including graphic ones, there you should check your 3D settings, they might be way too high for smooth playing. Also, nowadays 4GB of RAM is the lowest amount of RAM to play most of games.
