Playing Gta IV on pc wiht a 680 4gb evga card, and getting about 35 frames at 1080 while recording, i want to get back to recording at 40 frames at least but i also would like the 4-5k super sampling resolution i can tweak on the game (yes it runs stable) but when i run the 5k super sampling i get about 20 frames average while recording. i think it is mostly because of my graphics card. im not sure which way to go. my gtx 680 get a little hot bout 80 degrees celsuis but i was going to get a liquid cooler for it and see if i can oc the card. but i realized there are better cards out there. im not sure which way to go. my questions is should i just sli another 680 so i can get more frames? or should i buy a new single card and sell this one. 780ti or 290x? please help thanks
