Excuse me, but I have a fairly cheap laptop right here that I use for moderate gaming, and it has never overheated. I don't even use a separate laptop fan, either, but with one of those it's impossible to overheat.
One laptop =/= statistics for a lot of laptops.
Anyway, with the Alienware, you could shave off $300 by only having one 4870, and you could also downgrade your i7. I'm not that good with processors, so would anyone be able to recommend what would give him relatively good performance?
i5 520M 2.4GHz (2.93 turbo)
i5 540M 2.53GHz (3.06 turbo)
i7 620M 2.66GHz (3.33 turbo)
i7 720QM 1.6GHz (2.8 turbo)
i7 820QM 1.73GHz (3.06 turbo)
He currently has a i7 920XM 2.0GHz (3.2 turbo) in it.
You probably wouldn't need a SSD and would be able to shave $500 off if you went for a standard 500GB HD.
