don't worry about the price I don't mind paying a little more to get the best one !
is the 7950 better in everything compared to the 680 ?
7950 can overclock easy to the 7970 specs that or a 670. the money you save you can sli/crossfire later on and be better off
Ive acctually got that excact 7970 but the ghz edition i have a custom profile fan when i go gaming it puts itself to 50% temps never go over like 61-62c its normally stuck at 60c with auto fans it will probally hit 70c its a decently quiet card. overall Want to save money get the 7950 if you wanna get the best get the 7970 no reason to pick 680 over it. the 7970 ghz is faster. has more vram has a bigger bit interface. 7970 is a great card take it go home enjoy it
