I say since you're going water and heat wont be a problem that you grab the 5870 and waterblock, and then get another 5970 in teh future. Two 5870s will pwn a single 5970 I think.

There is no game ATM that a 5870 can't run IMO, unless you're one of those "It sucks if it isn't 60fps even if it doesn't suck" types.
I would do as suggested above though, and see what happens.

At his resolution though, he is probably fine with a 5870. But the 5970 should max anything he can throw at it for atleast 18 months. The 5870 will probably need to be upgraded to 2x 5870s after about a year if he still wants to max games.
I think he will save money in the long run by going with a 5970.
