I was curious if any computer/MAC gurus [ahem...Nate] could help me with a question or two...?

I just upgraded my MAC to 10.6 Snow Leopard. I am want to run bootcamp for essentially one maybe two PC-based software. I was thinking of loading Windows XP as people have told me it is quicker than vista if I will only be using it to run one program on my MAC.

Also, where can I get the best deal on XP...or whatever is recommended for me. I don't need office and all that, I have everything else on the 'MAC side'. I don't want to buy parallels or whatever it is...I priced those and it isn't worth it to run one program I am looking to load.

Does this make any sense?

Thank all!
