If money isn't an issue I would go with this one.

Nothing against brands or anything, but dual slot coolers are better, especially if you have a case with bad ventilation around the GPU. I just recently got an aftermarket dual slot cooler for my 8800GT. It was heating up my whole computer, even with a slot fan right above it. This card goes on sale a lot though, I saw it for $60 a couple months ago.
The only problem with that is dust. But that's nothing compressed air can't fix.
i would go with that....good price and decent gpu :good:
By the way...i run the rig in my sig on a Gigabyte SuperB 460W and have been for ages....no problems whatsoever.
