Some one got their hands on these new babies before the public release and that can only happen on the GPU production home town in China, Bellow there first leaked benchmark tests to share of these new great cost/performance effective graphic card comparing the two new GTX 660 and GTX 650 versus the GTX 660 Ti, of course the ranking is clear even before benchmarks, but how these card perform depending on their prices, or when setting a GTX 660 in SLI (later we will provide this one), we will post a comparison with the previous generation GTX 560 soon.
