While Nvidia's GeForce GTX 680 Kepler graphics card still hasn't gotten an official announcement from the company, we're seeing a flurry of price speculation in anticipation of the card's release. Computer chain NCIX has been spotted posting product pages for the card (both MSI and EVGA varieties), listing it at $579.99 and letting customers add it to their wish lists, though the pages have since been taken down. In addition to the price, the pages also indicated that the MSI card will be running at 1056Mhz and include 2GB of GDDR5 video memory clocked at 6GHz. While the EVGA version's listing didn't include graphics processor or video RAM clock speeds, the SuperClocked branding indicates that it will be factory overclocked. We also noticed that Google indexed another NCIX page listing a Zotac GTX 680 running at 1006MHz (below). Both 1006MHz and 1056MHz are expected to be stock speeds for the new card, with the GPU dynamically adjusting between them.

In contrast, we're hearing much lower prices from folks claiming to have an inside line on the suggested retail price. Fudzilla is reporting that resellers received a recommended retail price of $499 from the company yesterday — down from an expected price of $550. Of course, it's impossible to say with no official word from Nvidia, but we'll keep you posted if we hear any new details.
