It only launched a few weeks ago, but it looks like NVIDIA could already be set to cut the price of its top-end GeForce GTX 280 graphics card -- a move that would be prompted, as you might have guessed, by AMD's cheaper but powerful Radeon HD 4800 series. According to HotHardware, that word comes from "multiple NVIDIA board partners," who say that the card could be dropping to as low as $499 (the same as AMD's competing card). One board partner reportedly added that the price "may be a little higher, or potentially even a little lower." Obviously, all of that is still up in the air until we hear from NVIDIA itself but, as HotHardware points out, it could certainly pay off to hold out a couple of weeks if you've been considering taking the plunge on one of these.
