Probably because the GTX 560Ti is a fully functional GTX 460...which overclocks like hell on wheels. It probably doesn't take a genius to work out that if Gigabyte are binning a 1000MHz SKU -and offering a three year warranty into the deal, then the stock GPU has a reasonable amount of overclocking headroom.

Not bad for a GPU nominally binned at 823 / 1004...with that kind of potential ready to be uncorked I guess both(?) of you will be itching to buy one....thought not
Trolls!....DIS-MISSED!
