Well, I’m finding the 64bit version of Windows 7 works pretty well. I have most of my applications running again, using the 64bit versions if I could find them. The SSD drive is working great and I'm just using an external drive enclosure to get around the space limitations.
I’ve been rendering some of my models with the 64bit version of POV-ray. It seems to be working great. Not a huge difference, but some. It was interesting to see that memory and graphics each seem to get a speed boost. Overall, things are peppy, but some of that is probably due to completely reloading my machine with a clean copy of Win7. So far, no complaints.
