OCC has published a new review on the XFX GTX260 XXX SLI

This pair of GTX260s coming from XFX is nothing short of impressive. They feature an awesome looking heatsink and the bundle it comes with is all you need to get started - a couple adapters as well as the award winning Call of Duty 4. This is also the latest version of the 260, equipped with 216 processing cores and each of those are clocked to 640MHz, which is 64MHz over the standard edition. That's better than nothing, but since I just cannot settle with factory settings I, of course, overclocked these cards as much as it could. I was able to take the cores to 732MHz, which is pretty decent headroom. Obviously, the GTX260 is a very good performer, but as you have seen, a pair of them in SLI performs even better. The twins won every single benchmark of our suite except for Futuremark's 3DMark06 which, for some reason, has always performed better on ATI video cards.
