That's a nice system you're looking at, but Is suggest you look at a local electronics store. You'll be glad you did, I got my comp for $500 it's 4 gig DDR3 ram, (upgradable to 8 gigs) 2 AMD Athlon 2.7 GHz cores, and comes with Windows 7 Home Premium 64-bit. (What computer doesn't come with Windows 7 64 bit? Haha) But anyways, it's not a beast, but it runs most of my games at 60 fps, like Borderlands, Half-Life 2 ep 1 & 2, Team Fortress 2, Portal, and more. I'm really happy with it, just make sure for that price, you're happy. If you're like me, and went from the oldest piece of crap computer in the world anything new will do, but I made sure this was the right choice. Just got it this year from a local Staples store.
