NVIDIA's been on a hyper-competitive tear lately, and while the latest rumor isn't quite on par with Roy Taylor saying that the Intel CPU is "dead," it reinforces the company's new win-at-all-costs attitude. Seems ATI's upcoming RV770-based Radeon HD 4800 might threaten NVIDIA's dominance of the high-end graphics market, and that's just not acceptable -- so the company is planning on pushing up the release of the GeForce 9900 to July. That's one billion transistors and GDDR3 memory, if you haven't been memorizing rumored graphic card specs -- we're guessing that blue screen of death will render mighty fast on that rig.
