I am going to try the 43.03 and 40.71 dets but I suspect that they will be slower.
What chunter says seems to hold true with the new rigs P4's etc. and WinXP and full blown G4's and above but on humble systems like mine with the trimmed down bog standard MX cards there is no benefit in the new drivers as they seem to be tailored for the high-end cards/systems.
I hope I am wrong so I will test and see.
cheers
