Thank you for the welcome!
And I guess your answer pretty much nails it.
Actually, I am in the middle of transferring my digital audio work back to the PC world from the Mac.
The software I use for that, Cakewalk Sonar, is available 64 bit, but everything else I have is 32.
But I also have all the typical Office software, Visio, some development programs, etc. on it.
I know I should dedicate an entire machine to just the audio/video work, and I'm sure these forums will help me figure out what hardware to get.
For now, I'm stuck in 32 until I grab another PC.
I am surprised that there aren't loads of games for 64 yet. I'm not a gamer, but it does seem like the gamers are on the forefront of performance. They must be chomping at the bit (so to speak).
At any rate, thanks for the response.
