Does temperature really effect GPU performance?

[gergy008]

I just read in the CPU forum that a CPU under higher temperatures should not be slowed down by heat, Well it does but the effect is like 0.000000001%, Nearly nothing.

However, I do find my GPU gives better fps if the temperatures are lower, And I'm talking like 60 fps 30.0C and 18 on 47.0C

How would heat effect performance?

It shouldn't at 47c. I think your card is failing.
