Thanks fusionblu for the info and LifeOnMars for ebuyer link.
One question, how significant of an upgrade (GTX460 Super OC) will this be from GTX280?
Thanks
To be honest it is hard to say how significant the upgrade will be as it depends on what you are going to use the graphics card for, but it should be better at playing newer games as it supports DirectX 11 and it does have superior specifications such as the memory being GDDR5 instead of GDDR3, a memory clock which is more than 3x the amount of the 280 being at 4000MHz where the 280 is at 1105MHz and also that the 460 does have a higher Core Clock and Shader Clock specifications too.
The real improvement along with the specifications would have to come from the build quality such as the high quality components as well as the twin fan GPU cooler which keeps the SUPER OC Graphics Card at cool temperatures at quiet noise levels (some find they hardly even hear the fans).
The specifications alone pretty much shows this is a much faster graphics card than the 280, although in my opinion I would say the real power would come from having two of these in 2-way SLI like I have for the OC predecessor model of this graphics card (but truth be told that's just having a graphics card set up which should last for 2 or 3 years of gaming until the next upgrade, of course this set up would obviously be more powerful than just a single card and two of these should be able to beat a single 470, 480 and maybe a 580 while possibly being more energy efficient too).
If you was to ask me for a downside of this card, it would be that it cannot be put in 3-way SLI.
