Have the 2.66 mac pro with applecare and the video card has been acting up and apple said they would replace it. Gave me 3 options: send somebody out, send the new part and i mail back the old one, or bring it into the apple store. Given the mac pro weighs a ton (i have to bring in the whole computer) and i've been building computers for 10+ years i felt i could handle replacing the video card but they wanted a credit card to make sure that i would send back the old one. I know I should've asked how much but in the back of my mind it couldn't be more than $200. They sent me the invoice and i checked my card and they changed $562.76. I know I should've asked but really? $562.76? They're currently selling a gtx 285 for $450 and the 7300gt in it day, if it had one, was no way near that price. I've called apple and they've apologized for not letting me know, even though i take the blame on that one, and will refund the money and send somebody out to replace the card. Hopefully the hold will be lifted soon.
