Mac has nothing but problems with software but you're buying the name

Alienware is buying the name with good / decent hardware

HP is great hardware / great software / but over priced for no reason really

Dell LOL

Acer Personally I think they suck had a 1.5k$ laptop that died on me in less then a year

IMO go HP

So what is a good amount of ram

Win7=4gb+

vista=wtfvista?

XP=1-2gb


32bit? 64? 32 won't read anymore then 5

If you purchase a computer such like an "HP" computer, then 4 GB of RAM should be enough, but if you truly want a powerful gaming PC, then I recommend anything higher than 8GB of random access memory. 24 GB of RAM would be extremely amazing.
