Ok I run a i5 2500k at 3.6 ghz. I want to upgrade from a 670 to a 970. I play at 1080p. I have 16 gb ram. Will my older cpu bottleneck the new 970. I play new AAA titles plus older ones and indie games.

It s fine .

With stock clocks : 4790K will contribute to 18% more FPS . You have overclocked it 10% , so the difference would be 8-10% i5 2500K is a great CPU . .

Okay, compared to what is a mainstream intel CPU, the i5 4570 is like this:

- The Intel i5-4570 is 8% faster when running single-threaded programs.

- Multi-threaded performance 4570 is better.

- In memory-intensive tasks, 4570 has 6% higher performance.

- The Core i5-4570 processor incorporates AVX2, F16C and FMA3 instructions. Although these extensions are not broadly supported by applications yet, their support should improve in future programs.

- Power consumption of the Intel Core i5-4570 is lower.


So the whole thing is about 8% slower than i5-4570, which leds me to believe you might need to OC it 10% (which can be easily done without upgrading the cooling solution or raising the voltage) in order to clear out some minor issues with CPU performance and you're good to go.

I see so if OP goes to 4Ghz on his 2500K then we are talking less than 5%, always best to compare clock for clock.
