To help fill a model gap that no one told us about, NVIDIA has released its GeForce GTX 560, a slight step down from the Ti variant. Featuring a cut of 48 cores and the potential for wildly varying clock speeds, this card is a strange beast. But, we look to pit MSI’s ‘Twin Frozr II’ against our usual fleet of cards to see where it stacks up in the end.
At Techgage, we strive to make sure our results are as accurate as possible. Our testing is rigorous and time-consuming, but we feel the effort is worth it. In an attempt to leave no question unanswered, this page contains not only our testbed specifications, but also a detailed look at how we conduct our testing.
The below table lists our testing machine’s hardware, which remains unchanged throughout all GPU testing, minus the graphics card. Each card used for comparison is also listed here, along with the driver version used. Each one of the URLs in this table can be clicked to view the respective category on our site for that product.

When preparing our testbeds for any type of performance testing, we follow these guidelines:
To aide with the goal of keeping accurate and repeatable results, we alter certain services in Windows 7 from starting up at boot. This is due to the fact that these services have the tendency to start up in the background without notice, potentially causing inaccurate test results. For example, disabling “Windows Search” turns off the OS’ indexing which can at times utilize the hard drive and memory more than we’d like.
The most important services we disable are:
The full list of Windows services we assure are disabled is large, but for those interested in perusing it, please look here. Most of the services we disable are mild, but we go to such an extent to have the PC as highly optimized as possible.
At this time, we benchmark with three resolutions that represent three popular monitor sizes available today, 20″ (1680×1050), 24″ (1920×1080) and 30″ (2560×1600). Each of these resolutions offers enough of a variance in raw pixel output to warrant testing with it, and each properly represent a different market segment: mainstream, mid-range and high-end.
Because we value results generated by real-world testing, we don’t utilize timedemos. The possible exceptions might be Futuremark’s 3DMark Vantage and Unigine’s Heaven 2.1. Though neither of these are games, both act as robust timedemos. We choose to use them as they’re a standard where GPU reviews are concerned.
All of our results are captured with the help of Beepa’s FRAPS 3.2.3, while stress-testing and temperature-monitoring is handled by OCCT 3.1.0 and GPU-Z, respectively.
