Going for intel platform would mean new motherboard and new cpu...just get 680 and get some overclock on your CPU. If you are playing at regular 1080 you are fine...true that i5 would get you better FPS but even your CPU is enough to play all the games above 40+ with 680
I almost got my 680 yesterday but by the time I got to check out it was sold out lol...anyway I think I'm gonna wait for nonreference. 680 is awesome it has 6950 CF performance in one card...
your gonna have to switch your mobo if you wanna go an intel processor. which id recommend but you arent gonna do that.
so at least get the top of the line amd..... which is still ***. but better than your first pick lol.
get an fx 8150.
for the love of god dont desert the 680. but you might struggle to get one right now they are selling out like hotcakes
