Any difference in gaming between OC 2500K and OC 8320

[ScorpioJonesy]

I have a choice between keeping one of my systems and selling the other but can't work out which. One is an OC 2500K at 4.2Ghz to 4.4Ghz the other is an 8320 at 4.5Ghz (maybe more if I pushed it). I wanted to know which is better at its overclocked rate with a single AMD R9 290 (not X). Would it be pretty much the same as the bottleneck is the GFX not the CPU?

It would depend on the game, whether or not it's gpu intensive. To a degree the gpu will be a limiting factor but the i5 would be the one to keep. Stronger performance in most tasks including games. Where the cpu isn't taxed as much by a game, the i5 certainly won't perform worse. There are a few gpu intensive games that scale well and aren't very cpu demanding where the 8320 might come close to catching up but that's the best it will do. That's true of the 8320 overclocked vs the i5 stock much less overclocked. Intel cpu's are capable of more instructions per clock making it difficult to compare frequency (speed). 4.5ghz on an 8320 is more like 3.8ghz or less on the i5.

Update: here's a link to a few benchmarks for comparison. Neither are overclocked and at stock the 8320 is at 3.5 vs the 2500k at 3.2. Figure their overclocked speeds you're referencing are also close so it's comparable results.

Going to keep the 2500K for the moment then and clock it up to 4.4. Instead I'm going to save and get a 5820K then sell both the 2500K and the 8320. That way I get the games running sweet but also my workstation requirements are sorted.

Sounds like a good plan, the 5820k is a good price/position for gaming/workstation use.
