We won't go into too much detail with our testbed since all the main information required is in the above image. Instead we'll cover the video cards that you'll be seeing in our graphs here today. The first is of course the overclocked PowerColor HD 7950 PCS 3GB card running at 1110MHz on the core and 5600MHz QDR on the 3GB of GDDR5 memory.
Outside of the PowerColor HD 7950 we've got the Sapphire HD 7870 OC along with two Tahiti LE based HD 7870 video cards. One is the Myst Edition from PowerColor, and the other is the Sapphire model which we overclocked to over 1200MHz on the core. And finally to round everything off we've got the AMD HD 7970 GHz Edition card for good measure.
The FPS Numbers Explained
When we benchmark our video cards and look at the graphs, we aim to get to a certain level of FPS which we consider playable. While many may argue that the human eye can't see over 24 FPS or 30 FPS, any true gamer will tell you that as we climb higher in Frames Per Seconds (FPS), the overall gameplay feels smoother. There are three numbers we're looking out for when it comes to our benchmarks.
30 FPS - It's the minimum number we aim for when it comes to games. If you're not dropping below 30 FPS during games, you're going to have a nice and smooth gaming experience. The ideal situation is that even in a heavy fire fight, the minimum stays above 30 FPS making sure that you can continue to aim easily or turn the corner with no dramas.
60 FPS - It's the average we look for when we don't have a minimum coming at us. If we're getting an average of 60 FPS, we should have a minimum of 30 FPS or better and as mentioned above, it means we've got some smooth game play happening.
120 FPS - The new number that we've been hunting down over recent months. If you're the owner of a 120 Hz monitor, to get the most out of it you want to get around the 120 FPS mark. Moving from 60 FPS / 60 Hz to 120 FPS / 120 Hz brings with it a certain fluidity that can't really be explained, but instead has to be experienced. Of course, if you're buying a 120 Hz monitor to take advantage of 3D, an average of 120 FPS in our benchmark means that in 3D you will have an average of 60 FPS, which again means you should expect some smooth gameplay.
