Thanks for looking. I ordered my Mac Pro, but wanted to see what the MR community thought of it. Here is what I got: 6-core 32 GB RAM D300 512 GB Hard Drive The 6-core, the upgrade cost was worth it, since it's so difficult to upgrade. The 8-core was just way too expensive. 512 is enough for me, since I can go to 1TB when I need to. My issue is with the D300 video cards. I thought it was upgradeable, but have been reading conflicting reports. Can it be upgraded? I don't need that much video power. Only gaming, IF I do it on this computer. What do you think of this config?
