We land at the blue colored premises of Gigabyte they just launched this particular product with the 216 shader processors as well but under yet another name the Gigabyte GeForce GTX 260 OC. And it’s interesting when you think about it really these are thus the 216 Core versions of the product offering 10 maybe 15 more performance yet Gigabyte didn’t overclock the product at all. Which is kind of weird if you tag a product as OC right
