Anyone installed Win7 64bit via boot camp. Like my iMac I only use Windows and would repartition the SSD to the largest NTFS partition possible. How will CS, AutoCad and Office run?
I installed Win7 Pro 64-bit on my Ultimate 13". It works great. I don't use any of the programs you describe, but I have used Quicken and Windows XP Mode. I get a Windows Experience Index of 5.3, with the disk component at 6.9.
There's a bunch of threads on this already, plus you might have some luck searching the Windows on Mac forum.
