I have embarked upon my first build. My question is about Windows XP OEM vs. Retail. As everyone probably knows, the OEM is much cheaper. However, I have heard that they are not bootable, nor do they have drivers to support, among other things, ethernet or video. Can anybody tell me what, exactly, do I need to get my new computer up and running if I use OEM? Would I be better off spending the extra $90.00 for retail? Will I have the same problems if I buy the retail version?
