Today we'll be comparing the EVGA GTX 770 2GB SuperClocked ACX against the reference GTX 770 2GB at stock and at 1153MHz / 7664MHz QDR to see how the overclocked card performs against both the stock clocked card and the best clocks we could get out of the reference clocked version.
Along with the GTX 770 2GB setups, we've also got two reference GTX 650 Ti Boost cards in SLI, along with the reference GTX 780 3GB. On the AMD side of things we've included the PowerColor HD 7950 2GB which we've overclocked to over 1100MHz on the core, along with the reference HD 7970 GHz Edition to round things off today.
I want to mention the edition of the latest 3DMark in the form of the Fire Strike benchmark. Along with that we've also dropped Metro 2033 and replaced it with the newly released Metro Last Light. It has replaced the standard resolution and AA / AF Metro 2033 tests.
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.
Why are some graphs incomplete?
Adding new game benchmarks is a long, tedious and time consuming task as every video card has to be re-tested in those new benchmarks. Because of that reason we have always just evaluated our benchmark line up every six months. To stay up to date and current with the latest benchmarks and games available, we've changed our approach to adding new benchmarks.
Our benchmark line up will progress and be updated as newer more intensive games with benchmarks comes to light. While this will mean that initially you may only see a single video card in those particular graphs, as the weeks go on and we test more and more video cards, the results will grow quickly. This will help keep our benchmark line up as up to date as possible as we introduce and remove games on a constant basis.
