[citation][nom]kawininjazx[/nom]Do they not know how to build a PC? Core i7 with a GT430? How about an i5 and take the $80-$100 you saved on a real GPU?[/citation]
As said, it was a build just to see what they could use for their new UI.
And I am sure they know how to build PCs. Most every one who works at VALVe are PC gaming nerds, like us. They also have a dedicated IT room that builds and maintains PC systems.
As for the new UI, I doubt it would be anything like metro but something that will work on PC monitors or TVs. A lot of people didn't like the current UI at first, I didn't mind it, but now most don't seem to mind it either.
As long as I can get to my games without too much hassel, I am perfectly fine.
