Poised and waiting for ATI's latest graphics card to hit, Nvidia immediately fired off the 9800 GTX+, a nimbler version of its behemoth 9800 GTX, aggressively priced at $229 to put serious pressure on the $199 HD 4850. Benchmarks comparing the two weren't available yesterday, but PC Perspective has 'em up now. In short, while the HD 4850 can mostly keep up with Nvidia's older, regular 9800 GTX, the steroid-injected 9800 GTX+ has enough juice to edge it out in almost every single benchmark. The Radeon HD 4850 has about a month on the shelf to itself before the 9800 GTX+ hits though. Check out PC Perspective for more graphs and numbers than your brain wants to deal with on a Friday.
