That's a great thing! Once AMD's Fusion is also available, we will start to see PCs again with some decent gaming ability out of the box. Makes me nostalgic for the early 1990's again!
This is a huge thing for 'Joe six-pack' because he/she can purchase a lower-priced PC and actually play some fun games on it without needing to install a discrete GPU. I know a lot of people over the years that are more or less computer-illiterate that gave-up on PC gaming because their 'brand-new' computer that cost $1000 couldn't even play any games they got for it. Hopefully we see this trend change and the PC is a viable platform for everyone to use for gaming. Sure, a discrete GPU allows you to crank-up the resolution and eye-candy, but playability for the average user is important too. Exciting times.
