Price & Availability
This is not a soft launch - the NVIDIA GeForce GTX 680 is available for sale at e-stores right now, if you can afford the US$ 500 (RM 1,500) price tag. The price isn't too expensive since it's smack in-between the price of the AMD Radeon HD 7970 and the AMD Radeon HD 7950. However, you might want to hurry as it seems that TSMC is having yield issues with their 28 nm process and the GeForce GTX 680 might be hard to come by after the launch stockpile is sold.
