MSI GTX670 OC Power Edition Review
What a hell of a lot of performance is available from the MSI GTX670 OC Power Edition.
For a start it comes out of the box with a good 100MHz overclock when compared to the reference card, and this is enough to move it consistently ahead of the reference card in all of our testing. Sometimes it even gets close to or passes the bigger GTX680, so there is no doubt that if you're the type of user who prefers to just 'plug and play', the MSI GTX670 OC will definitely tick all the right boxes.
More impressive is the overclock we were able to obtain. 1256MHz. A full 200MHz higher than we were able to get from our reference card. This is with only a tiny increase in the core voltage which, as you could see from our temperature results back on page three, didn't push the idle temperature up much and didn't change the load temperature at all. It's not only the GPU Core that overclocks well either, as the memory saw similar gains.
Often we've found that an overclock doesn't always give the increase in performance you might expect to find, yet the MSI nearly always saw a significant improvement in our benchmarks, regularly matching the GTX680 which, let's not forget, was tested on a beefy hexcore 3960X rather than the quad-core 3770K. It shows how few titles take advantage of multi-core processors.
The cooler is impressive in terms of its ability to disperse the heat and keep the GPU cool. Even after a massive Unigine loop we still only saw a maximum 70°C both at stock and when overclocked. The fans though are much less impressive. When idle it's pretty inaudible, but nearly any load introduces the kind of noise that we haven't heard from a GPU in a while. It seems that with the cooling, or at least their choice of fan, MSI need to go away and take a fresh approach.
But that's the only fly in the ointment, and the performance is such that we will overlook this slight niggle. Available for around £300 and with more performance than anything available for a similar amount of money, with the added benefit of insane overclocking headroom, the MSI GTX670 OC Power Edition is one of those cards that we can give our coveted OC3D Gold Award to without any hesitation whatsoever.
