Approx GTX 550Ti HD6770 level of performance.
Really depends what game, BF3 @ 1080p medium ~ 20-30fps as you run around. More to render = lower FPS.
I've just replaced my GTX280

Hi,
I went from a GTX280 OC2 (650Mhz edition same speed as GTX285)
to a GTX580 twin frozer II , it was a nice increase BUT not earth shattering, I game @ 1920 x 1200.
If I knew then what I know now, I would have waited longer for the next gen stuff

Really? I just upgraded to a GTX560Ti and it's 2 -3 times faster at the same settings. A GTX580 should be 3-4 times faster!
You seem to be forgetting the 280/285 was Nvidias flagship single GPU card before the 480 was released and even today it's still quite a powerfull card.
http://www.anandtech.com/show/4221/nvidias-gtx-550-ti-coming-up-short-at-150/17the GTX 550 Ti could almost be a decent replacement for the GTX 460 768MB
550Ti has the same number of cuda cores as the GTX280/5
Finally, if the GTX280/5 is still such a capable card why is the second hand price around £50 ...
Faster core clock ratio, slower memory bandwidth.
Performance in the same ball park when you put it in the overall context of GPU performance.
GTX 285 is a fair bit faster than a 550Ti or 6770. I think I've pretty much proved that in my previous posts which you obviously haven't bothered to read!
