Hey guys
I recently built a computer (i5-4670k/660ti) and whilst I love the performance I'm getting, I'd love to see what some over-clocking could get out of it.
I bought an XFX Pro Series 450W PSU a few months before buying and assembling my computer, so I'm stuck with it for the time being no matter what.
Im sure that my current configuration on a 450W power supply is rather slim, but im wondering if I would be able to get ANY over-clocking on either of the components at all.

If its necessary, my motherboard is a MSI Z97 Gaming 3.

^^ Yes. You would be surprised at the power draw from overclocking. It is more than you would expect. You are on the edge with that setup already. You could, but only god knows what could happen. I would stay away from it.

Yeah, I just overclocked my GPU (120 Mhz overclock) and tried Skyrim. After about 2 minutes my screen went black for about 2/3 seconds. Assuming the draw went over the total possible power and caused it to momentarily close. Put it back to no overclock now.

Good call. You could consider upgrading to maybe 600 Watts for overclocking headroom.

That is a good idea, make sure you get a modular PSU that has good reviews and has 80+ Bronze or better.
