Yesterday, several Nvidia partners announced new GeForce GTX 260 graphics cards with 216 stream processors instead of 192. The new cards seem like an attempt by Nvidia to compete better with the AMD Radeon HD 4870, and they have the same $299 suggested retail price as the older, slower GTX 260s.
We took a quick look around major U.S. and Canadian online retailers this morning, and it looks like the souped-up cards have already become available. Newegg currently sells an eVGA GTX 260 with 216SPs and stock clock speeds for $300, before $8.97 shipping and a $20 mail-in-rebate. Buy.com has the same card for $342.52, and ZipZoomFly sells an "overclocked-in-the-box" version for $310. This latter model runs at 626MHz with 1053MHz memory, up from 575MHz and 999MHz on the stock card.
In Canada, NCIX already stocks a couple of GTX 260s with 216 SPs—again, both eVGA cards. The cheapest costs $240 CAD and comes with a $20 CAD mail-in rebate, while the "overclocked" variant is listed for $345 CAD.
