Radeon 7870 ghz edition or geforce gtx 650 ti boost?

[Skaidancer]

Hello, I'm building a mid range pc (600dlls) and this is the best i can do so far

Im new with all this PC build thing and the most important thing i want to know is what would my best choice for a Video card between Geforce 650 ti boost and a radeon 7970 ghz edition (also considering geforce 670 gtx and 760 gtx with more budget but dont know if worth it).

I also want to know any opinions about if im doing something wrong, any troubles i can have in the future with this build, improvements on the components ( that doesnt get out of a 600 - 700 budget) and any recomendations you want to give me (but remember im new with all this so dont get too rough xd).

Thanks

Assume you meant to say 7870 in your title, as that's the one you have in your build.

As for whats better, the 7870 blows the Gefore 650ti away.

Wow i thought they where almost the same but i did know 7870 was better the thing is that i went to read some reviews in newegg of owners of the 7870 ghz edition (saphire) and a few being having troubles with the video card, and the 650 ti boost owners doesnt present as much complains (except in game performance)with the video card.

Here are some reviews that I used to compare
