[QUOTE="pigoo3, post: 1045461, member: 56379"] Thanks for all the info in those last three posts!:) Great to hear that you figured out you got a genuine Apple card. Sounds like you got it for a decent price...especially if it's an Apple card. Yeah that info about the 16 vs. 8 lanes is what I was looking for. My understanding is...the original 2006 Mac Pro has 4 PCIe expansion slots...1 of them is a "16-lane" slot...and the other 3 are "8-lane" slots. What I'm still confused about is...my X1900 card I'm pretty sure is installed in the 16 lane slot...and because of the cards fan...it blocks a 2nd PCIe slot. Which leaves me with 2 "8-lane" slots still available. What I'm not positive about is...if I can install a 2nd "double wide" video card in one of the 2 remaining "8-lane" PCIe slots...and have it work properly. I know that if someone wanted to run the maximum of EIGHT monitors on one of the original Mac Pro's...you could install FOUR Nvidia 7300 cards (like the one you have I believe)...since they are narrow cards without a big bulky fan. So I know that I could just get a 7300 card & pop it in...but the 4870 is a much better performer. Thanks again for the help, - Nick [/QUOTE]
