CPU limitation is something that we always talk about when it comes to high-end graphics cards. When we say this, we mean that the CPU is holding back the frames that the graphics card is capable of putting out. The less intensive the game, or the lower resolution you play at; this increases the chances of hitting that bottle neck.
There are ultimately three ways to remove the bottleneck on a high-end graphics card. First, increase the settings in the game; things like turning on AA and AF help. The problem is that this might put you at an unplayable FPS level.
The second option is to buy a new monitor that offers a higher resolution, something like 1920 x 1200 or even 2560 x 1600. This can be an expensive task and again the increase in resolution might take your FPS to a level that isn't playable.
The third and best option which doesn't have a negative impact on performance is by overclocking. This not helps remove, or at least make the FPS limitation higher. Unlike the other two methods, this process will give you an increase in performance, which is ultimately what you want.
So what exactly have we done today? - We'll, let's have a look at the Test System Setup and a quick rundown on what we're doing here.
