MSI GTX 460 1 GB Cyclone is arguably the (or one of) best 460 available right now.
What resolution is your monitor?
The GTX 465 is fairly comparable, and to help move them nVidia is giving away copies of Mafia 2 if you buy a 465/470/480 right now. LOL So there's an advantage there.
Over all though, I just generally like the GTX 460 better. It's more refined, less power, cooler, etc.
Here's a direct comparison between the 465 and 460:http://www.anandtech.com/bench/Product/180?vs=161
They kind of trade off, where one beats the other.
