Futuremark today released the latest installment in their benchmark suite, 3DMark05.  There is of course a free download version, but you'd be better off heading to Fileshack to get it than trying anywhere else.  I'll link to a view previews of this software as I see them. 

Tech Report -- a good technical discussion and great set of benchmarks for a majority of program

DriverHeaven -- some screenshots and brief technical discussion

Hexus -- good look at it as well
