Ok I know this is an old topic and on paper the 770 is better. But I cannot find any heaven 4.0 benchmarks for the GTX 770 so I can compare notes. I do find many for the gtx 680 and 670. I am using the PNY GTX 770 which is basically a referemce 770 with better cooling. I find the games get simlar results to other 770's but my Heaven and valley scores are lower than peoples 670's whad up wit dat?
