[Build Help] Have a power-hungry, loud, hot GTX 470 and want to replace it with something newer and cooler

Pretty much what it says on the tin. I do a lot of dual-monitor things and the Fermi is just way too hot for my liking. Running at 75 - 80 C at idle on my dual monitor, and it's a pain in the ass to get it below 65.

I'm looking to spend maybe a max of $250, with a preferred price point around $200.

I do also game a bit, but nothing too intensive, and I'm not looking to push modern games to their limits.
