This is starting to look expensive... It's been a long time since I've done an upgrade install, but there is a chance that the upgrade installer doesn't need a running XP -- it may just need to "see" the original XP disk. Some searching on the internet probably can confirm this (or not :). Regarding the need to buy a new license, that depends, and in the generality that it has been stated it sounds wrong. If you have an OEM license, then the license is bound to the system (including the mobo), and the minimum you have to do is to call Microsoft, but even that isn't guaranteed -- they normally see a mobo change as a system change. If you have a retail license, it is not bound to any specific system, and re-activation should work normally. (After too many re-activations you still may have to call Microsoft.) While in theory it should work to move you current installation to a new mobo (search the web for tips), I side with Jim and think that a reinstallation has its advantages. You can create a separate partition on your existing disk or get a second disk and try a new installation there. This tells you whether this is possible in your situation (upgrade and all that).
