As seen on the Steam survey, Vista with DX10 graphics is less than 9,5% of the market.
It'll be fun hearing about all the hot air generated around the driver issues and inevitable underhanded tactics, but what a waste of effort, really.

that hasn't released a new WHQL 8 series driver since DECEMBER?!!?!

Is it just me or have graphics card got really really dull over the past couple of years? 

No real innovation other than racking up the horsepower.
It says something that a pointless benchmark tool causes a stir.

Graphics card power is now only of note depending on what size screen you want to use. There are now options that can cater perfectly for whatever screen size you want for some time now. 

I bet all those benchmarks will be done at 1280x1024 which makes them all the more irrelevant. Bring back the days of Quake2 and a 4fps boost was news worthy! lol
