I know this is a mac forum and my question is 'pc' related but please help me out. I am looking for a processor for my new hackintosh and the one I'm looking at is around £150 for the retail version. However, I've just seen one on ebay for £120 buy it now with a best offer option and the seller has feedback for selling one of these cpu's for £100. Apart from this cpu being OEM (without box, fan, etc) what are the risks of going for the one off ebay? Any advice would be fab.
