As another point of reference, I recently purchased a Thunderbolt
display and also the Mini Server quad core i7. Now, my application
is primarily an engineering work station. I use Parallels quite often
running Windows7 Pro. With 2 cores assigned to the virtual machine
and 2 for OSX, I have no system slowdown whatsoever when moving
back and forth between environments. The hardware simulations
that I do in Windows flies while I do CAD work on the Mac side.
There is also no video lag on the Windows side when I am doing
schematic or PCB layout.
I also, use Photoshop on it for processing my photos and sharpening
and and also Neat Image processing is almost instantaneous.
(34-35 meg images)
I have also done some Handbrake conversions of DVD level
video and have had conversion frame rates of 35-40. Settings
were High Profile, Constant Quality of 17.
Also, I have 8 gig of RAM installed which allots 512 meg to the
graphics card. I also, have server functions turned off.
64 bit Geekbench score of 9250.
