You will see very similar performance in a GTX 670 in comparison to a 680, for nearly $100 less. Consider an OC 670.
Except for that he put 660
For roughly the same price, you can get a 7870 which is a stronger card

You think I would get better performances with sapphire 7870?
Can I even put it on my motherboard..is it compatible?thanksAnd do ati cards work good on intel cpu?
How about MSI GTX 660?I heard stock speeds are almost the same as Sapphire 7870?thanks for answer
Stock speeds don't matter, they are a different chip so cannot be compared just by looking at performance statistics, only by comparing in benchmarks. The 7870 is a stronger card
Is it a lot stronger or not?
yep, the gtx660Ti would be faster then an hd7870 (not by much). But it's much more expensive
