So right now I'm looking to replace my gaming rig's graphics card, and after some advice and looking at reviews I've settled on either http://www.newegg.com/Product/Product.aspx?Item=N82E168... or http://www.newegg.com/Product/Product.aspx?Item=N82E168.... They're not the greatest, but $240 is about as far as I can go. I'm currently using an old EVGA gtx 460 and wondering which of the two (or any other cards in that price range I missed) offers the greatest increase. Any help would be appreciated. I have an Asus Rampage 3 Formula mobo, 6GB of ram, and a 950w psu in case that matters.
7870 is in most cases slightly faster than a 660, although you really can't go wrong with either. If you have any specific games you want to play mostly (or want better performance on that game), we could offer better recommendations though.
