:O

At what cost

[Luay79]

Off of my head and worst case scenario, same price. Should cost less due to smaller chip.

Seems to be a duallie

BUT Is it actually close to being something credible......?

[Soultribunal]

I would take this with not a grain of salt, but possibly the whole container.

Lets wait and see what actually comes further down the road.

Ooh, can I make up some specs too? In 2013, nVidia will release the GTX 890, which will get 240 FPS in Crysis, and use 4 kilowatts of power! Prepare for site traffic, Mr. Beaver!

If the HD 6000-series taught us anything, it is that even the best plans can be destroyed if a manufacturing process is not yet ready...
