64bit is the future. Step into it!
I would only recomend going 64 bit with a new computer. Alot less headaches. If you are getting a new computer, the I highly recommend going 64 bit Win7 and 64 bit X1. I have 12 gigs of ram, and have X1 (and 8.5) is very stable. The occasional crash, but for the most part it's great. You won't look back. I run everything in 64 bit, at 24/96 and I'm loving it. If you have an older computer, I would wait on upgrading to 64 bit.
I have to agree with A1, 64 bit is the future, I did it on a new computer rebuild that included Win7 and X1 all new, plus you can use all of your RAM (in my case 12 G, new).
