Both the DFI nF4 and the Chaintech VNF4 are slightly slower than the K8T890 boards with roughly a 2% difference seperating the Soltek and the VNF4.
UT2k4
Again, the VNF4 is a touch slower here to the tune of about 2% behind the front runners.
Half-Life 2
The VNF4 distances itself from the Gigabyte board quite nicely but is not quite on pace with the front runners.
DOOM 3
Not much needs to be said here that has not already been done so. Again the magical 2% comes into play because that's roughly the gap between the VNF4 and the DFI/Soltek boards.
