Ok, so I'm thinking about buying a Dell XPS, or maybe Dimension, I'm not sure (I want to be able to run Crysis really well, I'm looking at buying late summer). Here's my question: Does Dell XPS computers come with Intel 64-bit processors? I've heard 64-bit is the future, and I need to know what kind it is, so I know which version of Vista to buy (32-bit or 64-bit, I want a 64-bit). The thing is, Intel doesn't make it as clear, especially when configuring on Dell site, they only give you the basic outline.

 

So, does Intel make 64-bit processors, and does Dell use them? I'd prefer to buy from Dell, and I'm not sure they will give me what the want.

 

So which processors are 64-bit from Intel, and is there like, some site or something that can tell me which are and which aren't, or how to tell?
