IMO The 460 would be a nice upgrade. Quieter and less power, look better and be faster. But check Toms lists At Toms hardware
I thought comparing one of my GTX 280s to my older dual 8800GTS 512 cards was pretty comparable. Some games, such as Crysis, ran a touch better on a single GTX 280 over the 8800s in SLI, but for the most part they traded blows.
Dual GTX 280s in SLI, in certain games, can run better then a stock clocked GTX 570....so they are comparable.
To say a GTX 280 is as good as a GTX 460 (especially the 1GB version) is stretching things a tad, but it's a decent place to provide an idea of what to expect out of the newer generation GPUs when folks are upgrading from the 8xxx, 9xxx and GTX 2xx series.
So, if the TC was to grab a GTX 460 (even the SE) version, he'd be running roughly on par with a dual 8800GTS 512 setup or a single GTX 280. In the end, it would produce similar (if not slightly better at times) performance, less heat and use less power.
I see nothing wrong in going this route if you don't really game much anymore and you're looking to trim your PC down. Just my two cents.
