Retail stores like Best Buy are selling PC games and PCs with integrated graphics at the same time and they are not talking about the difference [to more capable gaming PCs]. Those machines are good for e-mail, web browsing, watching video. But as far as games go, those machines are just not adequate. It is no surprise that retail PC sales suffer from that. Online is different, because people who go and buy games online already have PCs that can play games. The biggest problem in this space right now is that you cannot go and design a game for a high end PC and downscale it to mainstream PCs. The performance difference between high-end and low-end PC is something like 100x.
And I have rocked onboard video-nforce implementations aren't half-bad and will run older games pretty decently-just not cutting edge.ATI and nVidia have decent onboard offerings, but those companies have very little market share compared to Intel. Intel pretty much owns the workstation motherboard industry - ATI and nVidia are mostly relegated to do-it-yourself systems and high-end gaming systems (like Alienware).
