GeForce GTX 560 In Nvidia's $200 Range
This story was conceptualized as a means to compare graphics card coolers from different vendors. Because no two GPUs have the exact same overclocking headroom, we wanted to take one GeForce GTX 560 and drop solutions from Asus, ECS, Galaxy, MSI, and Zotac onto that bare board. With thermal, acoustic, and performance data, we would have been able to give you a definitive answer as to whose heat sink and fan combination does the best job of pulling heat away from Nvidia's GPU. Surely, this would have been great information to have when overclocking.
Unfortunately, that plan was foiled by a number of variables that we simply couldn’t overcome to our satisfaction. For example, the cooler designers employ a surprisingly diverse range of fan power cable plugs, which aren't interoperable with any one card's connector. Moreover, fan temperature profiles vary from one card's firmware to another's, affecting our thermal and acoustic results.
With five GeForce GTX 560 cards in-hand, though, we still had the makings of a respectable round-up. So, we abandoned the idea of isolating cooler/fan effectiveness and forged ahead to bring you a comprehensive look at five examples of Nvidia's roughly-$200 contender.

As you can see, there’s a wide range of specifications applied to these cards, none of which match Nvidia’s reference 810 MHz core and 1002 MHz frequencies. The Galaxy model comes closest with its 830/1002 MHz clocks, but Zotac's AMP! edition goes all the way to 950/1100 MHz.
There’s a lot more distinguishing one board from the others than operating clock rates, though, as all of the coolers are unique as well. There's only one that matches the reference design. Some cards also include value-adds like games, and the Galaxy MDT supports as many as four display outputs and triple-monitor surround gaming. Of course, we also have to gauge how far our samples can be overclocked.
This dosent match with the above chart
I have the feeling that even a i5 2500k@4ghz bottlenecks a 7970 @1080p in most newer games.
If the GPU market goes the way it does, it won't take long that even midrange cards will be bottlenecked @1080p by the cpu.
