Will my CPU cause a bottleneck with a GTX 760/770?

I have a i5-2300 at 2.8Ghz / 3.1 GHZ Turbo Boost. I would like to upgrade my GPU, but I don't know if my CPU would cause a bottleneck, or not.

No, it will not.

That CPU will be fine for some time. Developers are usually forced to keep their engines light on resources because of the weak CPU's in consoles...

Depends what you're upgrading your GPU to.

It is in the title. I'm looking to get a GTX 760, or 770 GPU.

I was just worried that clock rate of 2.8Ghz would be on the low side for those GPU's.

It won't bottleneck, but that CPU may hold you back a bit for certain games that are going to be CPU intensive (games like BF4 and Watch Dogs). I wouldn't worry too much about it though since the consoles have pretty weak CPUs themselves.

What motherboard do you have? You can overclock your CPU by increasing your system bus speed, but it depends largely on the quality of motherboard that you have, and also the amount of bios options that it features...

On the same subject, I have a stock i7-920. If I went for a 280x would I be fine? Gaming at 1920x1200.

Holla.

that's perfectly fine

Great thanks!

OC the 920, that's what they're made for :P
