Would my i5 2500K at 4.5GHz be a bottleneck?
I've seen these questions so often. And I don't understand them.
If a 2500K@4.5GHz is not fast enough for a gtx670, then what are you supposed to buy, if you have a gtx670 ? And in particular, what are people supposed to do, who prefer to not overclock their CPUs ? A 2500K@4.5GHz is faster than a i7-3770K at stock speeds in games. And what if you have a gtx680 ? Or an overclocked 7970 ? Were those GPUs designed while the designers knew that they could not be paired with any CPU efficiently ?
And then there is the issue: when are you bottlenecked ?
Maybe a slower CPU can not reach 100 fps in a particular game. Only 40 fps. But then you can still enable lots of eyecandy on the GPU. And it won't affect the overall framerates. You can enable 8xMSAA, transparency, maybe SSSGAA even. High SSAO, high-res textures, high resolutions, etc. And always stay at that 40 fps. Is that useless ? Not if you value eyecandy more than high framerates. So you will get value out of your new videocard. And if/when you decide to upgrade your CPU later, you'll get the last part of value out of your GPU.
But again, I can't imagine a 2500K would bottleneck any GPU, even at stock speeds.
