Got the GTX 460 by Asus for my new build a couple weeks ago and it is bang for the buck. Got it for about $200, excluding the $30 rebate which I have not yet sent out.
Overclocked, it performs extremely well with stable temperatures. Hell, you can't even hear it when overclocked.
Here's the review.

Extremely easy to overclock as well.
