MSI's GTX 670 Power Edition is another formidable custom-design GTX 670 implementation. Thanks to its overclock out of the box, it matches performance of NVIDIA's much more expensive GTX 680 spot on. Compared to the stock GTX 670, the performance increase is 7% averaged over all our benchmarks.
MSI's Twin Frozr IV cooler does a great job keeping the card cool, temperatures are low, even at the increased clock speeds of the Power Edition. While idle fan noise is whisper quiet, noise under load is not optimal in my opinion. We've seen other GTX 670 cards deliver a much quieter experience under load, it looks like MSI keeps favouring lower temperatures over low noise as recent reviews have shown.
GPU overclocking potential of the card was in the typical range of overclocks we've seen on other cards, memory is just a bit lower, but the impact is relatively small. Considering that MSI is using a close-to-reference PCB design that just uses a larger PCB, these differences could be random though.
Price-wise, MSI's card is available in retail at $430, which is not unreasonable, other overclocked GTX 670s come at similar pricing. Given the currently available custom GTX 670 designs from other manufacturers, most of which are very good, I think it wouldn't hurt MSI if they dropped their price another 10 bucks or so, to draw more attention.
