ExpReview's got a table that summarizes the specs for the four graphics cards we're likely to see within the next couple of months from both camps. The Radeon HD 4850 & 4870, along with the GeForce GTX 280 & 260. The chart just puts all the numbers into one place so that they're easily compared. Good for quick reference.

Also, while there haven't been any solid release dates announced, nVidia has apparently changed the NDA date for the GT200, much to the chagrin of the Inq haqs. Looking like they pushed it a day, so the 17^th is now your target date; if you're eagerly anticipating such things.
