I'll be putting my system together this weekend. I was planning on giving Vista 64 a try, but I'd read that some of the testing apps out there don't work in Vista 64. Would it be recommended that I start out with a 32-bit OS for the hardware shakedown and then once I've got it stable where I want it, install the Vista 64? Or just not worry about the couple of apps that don't run in the Vista 64?
