i'm looking for a low power consumption but play games on medium.

was considering the hd 6850 1gb and gtx 460
and for low power consumption a hd 5770 1gb

thanks for your advices

Well, if that's the only store for you to shop at, what about the Radeon 6870? It's faster than all the cards you've mentioned.

These cards don't consume much power either....your PSU is far more than adequate.

I run a gts 450 and it runs all games at high or ultra settings with no hiccups..

Obviously not the best card but for the money you can't go wrong.. they're only 130 bucks. I personally use the asus geforce gts 450 1gb ddr5 but the site you listed has a different brand for sale with same price.

examples of games I play most frequently.. Crysis at 40+ fps on highest settings.. WoW at 60fps Ultra settings.. Black ops on extra high settings.. Starcraft 2 on Ultra settings and of course fallout 3 on high settings.
