So my Windows box is about 4 or 5 years old, and it wasn't a ballsy box to begin with. So the wife said she'd help buy a new one for Christmas for me. My main objectives are at least an i5 processor and an nVidia chip. RAM and harddrive specs are gonna be standard pretty much anywhere these days, so that's not an issue. I found an Alienware which has these standards. The low end has an i5 and an nVidia chip with 1 gig of VRAM. 4 gigs of RAM and a 1TB drive. By the time I get it, Windows 8 will be standard. Is 4 gigs of RAM enough for Windows 8, or would there be a noticeable lag there? Should I just spend some extra dough and get the Alienware desktop with 8 gigs of RAM instead?
