Heh, I doubt many XBox1 games used AA/AF, but the 8500's implementation of both was pretty bad (arguably just completely bugged in AA's case but hard to say - and an innovative but dubious trade-off for AF). And while the Pixel Shader was ahead of its time, it would also have been too late for Microsoft's original schedule. Either way this is pointless - NVIDIA wasn't chosen just for their GPU, but for their ability to integrate the northbridge and design the southbridge. For all we know Gigapixel (or later via 3DFX) might have won the contrast if it wasn't for that - wouldn't that have been hilarious?
