i noticed a substantial increase in speed and performance with windows 7 over vista and xp even. after i made a few changes, the first thing you should do is turn all the aero stuff off!!! go to personalize, then advanced and uncheck everything, that gave me around 1500 more on my 3dvantage score and bumped my fps up quite a bit with 5 clients running. and also turning off the before mentioned indexing and stuff. i use a program taht was linked in the forums some time ago for setting up symlinks within the right click context menu, it works flawlessly witn win7. i am extremely pleased with what ms has done, seems they have gotten it right this time, lets just hope they don't mess it up with a service pack or update. and the performance with multi-gpu's in sli and not, is astonishingly better as well, running a monitor per gpu, non sli is ridiculously fast now, nomore cross rendering, it works as intended now, at least on my setup.
