Guys I am planning to buy Mac Pro 8 core, I have a couple of question for people who have bought one and people with the info 1) Can I run Nvidia 8800GT (in main slot) and ATI 2600Xt in one of the other pci-e slots together 2) Where is the best place in UK to buy RAM for the new mac pro? 3) Can I run Tiger OSX instead of Leopard on the new mac pro (will all hardware work graphics card in particular) I need to run Tiger because checkpoint have not released a Leopard VPN client just yet (I hate checkpoint). (non of the other programs work. 4) what is the onboard sound card? is it any good compared to say creative labs Xfi etc... I will add more as I think of them.
