Hello, I was having some graphic issues with my new Mac Pro so I called apple care and they've sent me a DIY replacement card and now I have to mail the original card back. My question is, are the replacement parts apple ships new or used/refurbs? The card came in a little bubble wrap, anti-electricity bag inside of a padded box so I can't tell the condition of the part. It would really put a bad feeling in my stomach if I just dropped that much cash on a new machine last month, only to have used parts going into now. Anyone know for certain if their replacement parts are new? Thanks.
