Recently we saw the leaked pictures of the GTX460's PCB and then Nvidia announced the card officially in two variants.
Now though certain online retails have listed prices for the card, the 768MB variant has a reported price of $200 whereas the 1GB variant (which also has 25% faster higher memory bandwidth) retails for $230. Even though the GPU isn't as expensive as Nvidia's top range Fermi cards, it still has all the features including Advanced Tessellation, DirectX 11 and 3D Vision Surround Sound. Bothe variants will be on sale starting 12th July.
