Hello. I want to buy between this two graphic card, Radeon 7970 and GTX 770. Which one is the bes for me? And are this two fit into my casing. Here my specs.
Yes, they will fit.
Those 2 GPU are almost the same. AMD performs better in some games, NVIDIA performs better in some games too. So it depends what are you going to play.
GTX 770 do less noise, but heats more. At power consumption they are the same.
Here are some benchmarks - http://www.anandtech.com/bench/product/770?vs=829

That PSU should have enough amps. But I didn't find any info on the cables. You're gonna have to check it out yourself. You need to find a cable like this
If you do find one, then you should be good to go. BUT I would highly recommend getting a new PSU. Let me know if you need any recommendations.
