Test Setup And Benchmarks
Both the GeForce GTX 650 and GeForce GTX 660 are aimed at gamers with 1920x1080-capable displays. Because they serve up different performance levels, though, you'll need to tweak your favorite title's detail settings based on each card's capabilities. Because of this, we're putting the GeForce GTX 650 and its competition through less-demanding presets than the GeForce GTX 660 and its segment.
In addition to single-card testing, we're also testing the GeForce GTX 660 in SLI to see how it stacks up against AMD's Radeon HD 7850 in CrossFire. We're also overclocking the GTX 660 to see how well it does at its limit.
Finally, the Radeon HD 7850 that we had so many problems with in our Pitcairn launch story finally died on our test bench. We want to thank Jared and Mike at Itech Systems in Winnipeg, Manitoba for loaning us a replacement so that we could collect the data we needed for today's comparison.
