The best 770 model of the two above is the http://www.mwave.com.au/product/evga-geforce-gtx-770-su.... It is better because it has ACX cooling so it heats up much harder and it has a 3 year warranty. But I think you should get an EVGA GTX 780 because it has much better gaming performance. But if you are decided to go with the 770 then you should definately go with the ACX one above. I hope that I helped you.
