Introduction

After testing the GTX 580 at stock clocks there's clearly a little bit of a love hate relationship going on with the card. The one thing you can't take away from it is the performance that it offers out of the box.

Considering you've essentially got the performance of two slightly overclocked GTX 460s in not just a single PCI-E card, but more importantly a single GPU card, is nothing short of fantastic.

Low stock, though, and a high price tag is no doubt going to be a turn off for most people. Today, though, we try and add some extra value to the card with the help of MSIs own Afterburner software to see what happens when we overclock this bad boy.

Since we've already looked at the card, we won't go into any detail on it. Instead we'll just have a look at what clock speeds we ended up with and then get stuck into the performance of the card at the said clock speeds.

Overclocking

As we mentioned, we used MSI Afterburner and proceeded to bump the voltage up to give us some more room on the core. From the stock 772MHz Core we ended up with a nice round sounding 900MHz.

That in turn pushed the Shader clock to 1800MHz. As for the memory, we rounded that off to 4200MHz QDR. Not a huge gain on the memory, but that extra core speed should yield with it a nice performance increase.
