No not special edition. I think it was Smart edition or some other Acronym. But years ago when it came out I remember people trashed this card all over the place calling it Slow edition, suckass edition etc etc.
It's simply a cut back version of the original GTX 460. According to those who had them and benchmarked them, the different was negligible in real world settings but I honestly think there was a difference you could tell, and we're not even talking benchmarking figures yet. Anyhow, it's a cheaper version and it was around the end of 2011 when it starting coming out. There's far more better cards out there today for 'bang for your buck'!
