Introduction

There's been word floating around that the HD 5670 is quite the overclocker with it running into no problems achieving the maximum GPU clock of 850MHz that is offered via the Overdrive functionality inside the Catalyst driver suite.

With our Sapphire HD 5670 sitting around and not doing a whole lot, we thought it was time to throw it back into the testbed and see if we could not only max out the overclock of the card via the Overdrive feature, but also see what kind of performance increase we can achieve from doing so.

Since we've already had a good look at the Sapphire HD 5670, we won't be going into any major detail on the model. The one feature that's worth noting is that the card carries with it GDDR5 memory as opposed to some other variations which will carry with them GDDR3.

In saying that, let's jump forward to page two and see just how we went with the overclocking side of things before getting stuck into the performance.
