I attended GameFest 2010. I can't say much except that I want to work with DX11 even more than before, if that was possible. As a result, I just bought a Radeon 5450 from newegg. Sure, it is a rather weak card, but it is only $35! Plus, it is much faster than the reference rasterizer and it only consumes 19 watts at full usage!
Here is the card I bought:
It should hold me over until the Nvidia 400 series cards come out in a month or two.
Talk about perfect timing! The latest version of SlimDX was just released today. The D3D11 wrapper should be even more stable than what it already was.
