I think Valve at least successfully catalyzed the manufacturers to start thinking about more cost-effective prebuilt systems, small enough to fit under the TV, with a form factor that won't make them look embarrassing down there. I think the $450 range ones are definitely better than what's in that price range today. And if some of the pricier options can get a GTX 980 in there for under $1k, that's actually a pretty great deal. Unfortunately, the video cards I've seen in the lower tier won't really keep up with what's in the PS4/Xbox One, which will be selling for around $299 a piece by the time these machines come out.
