So I decided to try overclocking my EVGA GTX 770 in Precision and run Heaven for benchmarking. I got it up to +145MHz GPU clock offset and +75MHz MEM clock offset, anything more, while it runs, actually gives me worse results. I only really got maybe, 4-5 FPS increase from this overclock, I was expecting more lol.
Is there a limit in which GPUs don't yield better FPS?
Sorry if these are dumb questions, GPU OC'ing n00b here.
