Um... Tyler... I'm pretty sure your dead wrong. DEAD wrong.
Windows Vista has several problems. First of is Microsofts bloat problem: if you have the system resources, Windows will eat it. The more RAM Windows can find, the more RAM it will populate. Why do you think theres such a large amount of RAM clearing programs about?
Betas in general do not like gaming. ANd then theres microsoft betas, that just dont like anything without the quad colored window blazened onto the software box.
Personally, I dont buy anything microsoft untill I've had a few months to watch the first hundred flaws pop out. Then, atleat I KNOW what I have to deal with.
CPU PC systems should have a modern CPU.
RAM PC systems should have 512MB of memory or more.
GPU PC systems should have a DirectX 9 class graphics processor.
Apperently, a 64 MB video card is required for grapgics to be decent, and much for for areo. Microsoft itself says they're will be extremely large gaps in between what works and what works even marginally well.
