I am building my first gaming PC, and I am wondering how much I should OC my AMD FX-6300 to prevent any bottlenecking of my GPU (Gigabyte r9 270x Crossfire) I know most of you will say to not go that route for a GPU, but I got 2 r9 270x's for less than $200, so I am going that route.

Thank you very much, I am going to use the CM Hyper 212 EVO, as I am going all around for best bang for the buck.

Run your games and see how sensitive your games are to cpu capability.

Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
This will simulate what a lack of cpu power will do.


Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
set to 70%.
If your games react badly to less power per core, you will know that it is important to oc your chip to get more compute per core.

Few games use more than 2-3 cores. You might be able to get a higher oc per core by disabling some of your 6 cores.
Try disabling a pair of cores and see how much it hurts your games.
This will also tell you how effective an upgrade to a FX-8350 is likely to be.

Just going to tack on a little easier, more applicable way to detect "bottlenecks."

Run FRAPS or some other FPS counting software.

Run each of your games. Set the resolution to native and the settings to highest. All the way to 11. :p

See what FPS you get as you play for a little while. Once you have a good idea of your average FPS, drop the resolution to lowest. If your framerate did not increase, you have a CPU bottleneck and overclocking would help the game perform better.

Alternately, if you see a boost in FPS, then you have a GPU bottleneck. Alleviating this bottleneck is as easy as turning down the eye-candy. Overclocking your CPU will not help if your fps is determined by your GPUs.

Keep in mind, if you're getting 60+ FPS with a CPU bottleneck, chances are overclocking won't help you. (As you would have most likely reached your monitor's refresh rate.)

This kind of testing is the only way to know if you have a bottleneck or not.

Geofelt's suggestion to mess around with # of enabled cores would also be helpful if you were trying to gauge how beneficial a CPU upgrade would be.

Final note, to ensure a reliable "testing environment," make sure your computer is free of malware and any unnecessary programs that may be wasting CPU cycles.
