Introduction

Yesterday we got an opportunity to look at the MSI GTX 660 Ti Power Edition and found ourselves extremely impressed with the new NVIDIA based GPU and what MSI was able to do with it out of the box. Coming in under the Power Edition label, though, we'd normally just skip the whole out of the box performance and instead get straight into the overclocking side of things.

Due to the fact it was our first retail GTX 660 Ti, though, we wanted to see just what kind of performance we could expect out of the box. Today, though, we've thrown the video card back into our testbed and we intend to see just how this Power Edition variant goes with its Triple Overvoltage feature that lets us adjust the Core, Auxiliary and Memory voltages above stock settings.

Since we've already taken the time to go over the MSI GTX 660 Ti Power Edition in detail (hit the link above to see more), we'll simply be moving into the overclocking side to see just what we can get out of the card here today. From that point we'll quickly go over our testbed, cover the cards that will be in our graphs today and then simply get into the performance to see just what kind of boost the overclock gives us.

We really want to see what the overclock does when it comes to comparing the performance against not only the higher end GTX 670 and GTX 680 which has proven to perform stronger at the higher resolutions. We also want to see how it compares to the HD 7970 GHz Edition; the one model from AMD that tends to consistently be in front of the new NVIDIA offering. We also want to see if the overclock helps close the gap at the higher 2560 x 1600 resolution; an area that is constantly lacking when comparing NVIDIA video cards to AMD.

Overclocking

Having a look below we can see the default clocks on the MSI GTX 660 Ti Power Edition is 1020MHz on the core or 1098MHz via Boost, while the 2GB of GDDR5 memory comes in at 6008MHz QDR.

This compares to the stock 915MHz / 980MHz core clock we saw on the reference card. The memory speed is the same as the stock version.

As for the overclock we managed to achieve, you can see the core comes in at a very strong 1127MHz or 1205MHz via boost. This is a really strong overclock and should yield some strong performance.

If that wasn't enough, though, we pushed the 2GB of GDDR5 to a massive 7000MHz QDR.
