Introduction

The other day we checked out the MSI HD 7970 Lightning 3GB and in typical MSI Lightning fashion we found ourselves really impressed with what was on offer. Strong overclocking performance, a good out of the box overclock, awesome cooler and just a huge amount of features make it a stand out video card.

We figured what's better than a single HD 7970 Lightning 3GB overclocked, though? Two MSI HD 7970 Lighting 3GB video cards overclocked and in CrossFire mode! So that's exactly what we did - we organized another MSI HD 7970 Lightning 3GB, paired it with the one we had and then proceeded to overclock them both in CrossFire. Much fun prevailed, of course.

Because we've already looked at the video cards we're using in more detail in our original review, we don't need to cover it again. Instead for a more detail look check out the original review we just linked above.

Instead, we'll get into the good stuff pretty quickly today as we know that is all you want to see. On the next page we'll check out our Test System Setup and cover the video cards we'll be using in our comparison today. On the same page we'll also check out the overclocking ability of the setup. CrossFire always brings a slight hit in overclocking ability and we'll find out just how moving to the two card setup affects our maximum overclock today.

Once we've done that then we'll just get into the performance side of things to see how this CrossFire setup compared to other single card setup and CrossFire ones. So with all that said, let's get into the test system setup and the overclocking side of things to see just how we went.
