Hi guys,
I want to buy a new video card for my newly upgraded pc. Now i have Sapphire Radeon HD5770 1GB DDR5. I want to buy HD7870, and i want to know, will it be better to run this to card with crossfire, or will it just make it worse? And i want to know if 7870 is better than gtx660. I have only 200$.

You can't run cards that aren't the exact same model together. It just won't work. And no, the HD 5870 isn't better than the GTX 660.

The GTX660Ti AND the HD7870 GHz edition have more or less the same level of performance.
The HD7870GHz should be faster than the GTX660Ti but not by very much. It also has a 256-bit memory bus, instead of the 192-bit on the nVidia card, BUT here's the problem...the Sapphire HD7800s are extremely buggy. They did solve the issue on cards sporting serial numbers out of their specified range. If I were you, I'd even go with an HD7950 or an HD7870 from a different manufacturer.

If you can find an HD7870 GHz edition from a different manufacturer(avoid XFX), go with that.
If you can't, go with the GTX660Ti.

From all three cards you've posted, I'd go with the Gigabyte one hands down. That's definitely a great choice.
