I have the Asus GTX 770 2gb, Asus M5A97 R2.0 mobo and the Seasonic M12 II 620w psu.
Can someone tell me the max temps and the voltage and all that stuff in GPUTweak, so I can overclock it?

typically with the stock bios, you can max the voltages without damaging the card, but it WILL reduce the lifespan of the card (cant say by how much,)

otherwise with overclocking the card, start with the core clock, and go up by 100mhz to start. from there, run a gpu stress test like unigine valley for around half an hour
after that completes without crashing, you can start increasing the core clock by more until you get it to crash (go up in increments of 10mhz on the core clock until you get a video driver crash).
after you get your max core clock, repeat the same process for the memory clock

when you get a crash, dial back the core clock by 20mhz instead of just 10 to ensure stability.

your temps should still be pretty good...

your temps should still be pretty good, since even the stock cooler on the 770 is pretty great, but the max temp should be 80 on that card, and so if you are seeing it get to around that temp, increase the fan speeds or reduce the overclock.

increasing voltages alone will do nothing, but it will allow you to overclock the core clock ever so slightly more, usually for a minimal gain.
