Heres something worth thinking about; we all remember the GTX460 has 336 CUDA cores and has one of its PolyMorph engines "disabled", or as is more likely the case simply turned off by masking it in BIOS code. The important thing to note here is how the GTX460 (AFAIK) physically has 8 PolyMorph engines, but only 7 are in use. Now, my point is this; for 8 PolyMorph engines to be in use that would give you... wait for it... 384 CUDA cores. So this GTX560, could, in fact, be the GTX460 rebadged with a different BIOS enabling that unused PolyMorph engine.
