Came to $1163. It's almost identical to the second computer you listed. Except this has 6GB (which is plenty) and has a BETTER video card (yes, I do realize the other one has sli'd vid cards, but individually (and maybe not sli'd either...I'm not sure on that one), they aren't as good as the 4870...so you might as well just get ONE card and then cross-fire later if need be). Also, you don't need liquid cooling..it's just one more thing to go wrong. You can go through and customize one on their if you'd like anything different (like a bigger hard drive or something).
