Thank you for your reply.

Yes, I do realize my site is small. We are only about to hit our six month mark. However, based on our current rate of growth I am hoping to be in the big board arena soon enough. lol Well we hope anyway.
Really my question was asked to understand the thought process of moving into higher end hardware. I guess reading back, it can be taken as a no brainer. Of course, server loads and concurrent users will dictate the move. I suppose I will just work off the data I have and make and educated estimate on that.
Thanks again!
