NVIDIA's GeForce GTX 470 and 480 will only be available in short supply and at very high prices, a leak from within the graphics field claims. Although the company has promised a launch on March 26th at PAX East, boards based on the new architecture will reportedly only be available through the companies most loyal to NVIDIA and don't sell any ATI-branded graphics. The sources allege that "second-tier" third parties that sell both brands will have to wait until sometime in April.
