Anybody using HD7770 please review

I have the 7770 and its an awesome card for the price. Its the best bang for the buck, usually around $100. I have personal experience as I own the card AND I have a whole channel full of benchmarks using the card playing tons of games. Check out my YouTube Channel: www.youtube.com/thatechgamer

Heres a link for my videos for some games you were wondering about:

Crysis 3: http://www.youtube.com/watch?v=dWyt05RPU8w
Far Cry 3: http://www.youtube.com/watch?v=qcaNSuFUKhQ
and take a look at Tomb Raider: http://www.youtube.com/watch?v=HodA1tTbATM

I hope this helped, just check the video descriptions for an idea of how much FPS you should get.
 


Your rig has i5 3570k. i5 3570k and i5 3550 both are same almost, so will i5 3550 make any problem in game play??
 


Yeah, it should be fine. The lowest I would go is an i3 3220 or X4 980. But this is fine, it should be good considering its i5.
