>My projects are huge and I am wondering if a faster machine would give me faster builds. I am currently running on a Dell Pentium 4 3.4GHz with 1G memory using XP. Do you think there is something out there that would be significantly faster?

Do you have the project on the LAN or your local PC? I use VSS to ensure the project and all source code is on my local pc and check in/out only changed stuff. Rarely do I need a recompile all, but I find it way faster on the local PC.
