Looking to sell my GTX 580 while it's still worth something. Was looking at either a 7850 or GTX 650Ti boost to replace it with. I don't have the time to play games like I used too and if need be I could attempt another crossfire/SLI setup. I game at 1080P. Won't be going larger or multiple monitors. From TR's and other reviews, I should be able to get away with both cards at this resolution, even if I have to turn down some settings. What do think I should do?
You don't make it explicit, but it seems like you are okay accepting lower frames or lower detail in the switch - you are just looking to get solid 1080p performance and want to pocket some money in the exchange. I get that vibe since you use the word "replace" rather than "upgrade." Others seem to have read "upgrade" into your post. If I'm wrong, just stick with your 580 since it outclasses the HD 7850, GTX 650 Ti Boost, and GTX 660 or the difference is so small its not worth the money.
If you get lucky, you can probably sell your 580 for between $275 and $325 depending on how many GBs you got in there.
An HD 7850 or GTX 660 are solid choices for 1080p gaming as long as you aren't looking for rock solid 60fps or don't mind turning down the detail settings a bit on the newest games.

I recently got a 7850 because it was cheaper than a comparable Nvidia card and also came with Bioshock: Infinite and Tomb Raider. Nvidia's offer of in-game currency is laughably terrible. I like the GTX 660 better as a card based on reviews, but I just felt that the 7850 was a better overall value, especially with the games. The 650 Ti Boost looks pretty solid too. Your mileage may vary, but I would expect the GTX 660 to outperform the 7850, but not by a huge margin. That said, the 7850 has done everything I’ve wanted it to do so far, though I only game on a 720p TV.
