Benchmarking of windows 10 build 10061 vs windows 8.1 on the same machine

Question

After some of testing build windows 10 build 10061 with pcmark 8 and some graphics tesing windows 10 the major set back on performance drivers are not ready quite yet (amd drivers have major issues here) Also have issue with nvidia quadro drivers cl accelerated
not working other then driver is fine
Home Accelerated 88.77 of windows performance
HomeConventional 95.84 PCMark 8 Work Accelerated 2.0 95.22. On that test I though out dell laptop scores it was way off. PCMark 8 Work Conventional 2.0 98.41
PCMark 8 Creative Accelerated 3.0 90.66%
PCMark 8 Creative Conventional 3.0 98.56 These score were vs windows 8.1
Now the data for windows 10 build 10061 of the web browser mozilla firefox  95.94
chrome 95.85
internet explorer 99.28 (scores went from last build)
spartan against the windows 8.1 ie 101.69 faster. Score are still much slower the chrome or firefox .
Gpu drivers did  play role here
Their were 4 machine test here for this data.
intel q6600 with nvidia 460 with 6gb ddr2
dell laptop core 2 9550 cpu quadro 770 4gb ram
esxi box amd 1100 given 4cores  4gb ram
amd 8320 with gb ddr 3 and 5770 actuall has 2 but due driver issue only one was working

Answer 1

I would disagree. It does show were it would need work currently. If the amd drivers keep have problems I would not recommend the os to people that have amd gpu on machine. I hope that this os is one the better os for Microsoft. As pc gamer I would not run
os on my machine that cause lower performances on machine it makes no sense.
Contrary to your own unbiased opinion, making decisions based on an unfinished product is really a waste of time for the end user.  Yes, Windows 10 still needs work, but your benchmarks are totally useless for comparing an unfinished product to a finished. 
That's like counting your chickens before the eggs are hatched!!
