Ok, so I do video editing and Graphics. I just sold my PowerMac Dual G5 because I see the future death on the horizon for PPC with Snow Leopard coming out. My budget is right around 1500.00. I'm looking at either a newer 24" iMac with the 8gb Ram capacity or buying an older used intel MacPro. The pros with the Mac Pro is the capability of expanding. The cons, it's older and potential for issues are higher. The pros for the iMac. New ones have 8gb Ram Capacity and secondary monitor support. Newer and possibility for apple warranty. Cons, can't upgrade video card or install other cards such as RAID cards. I'm not doing any Motion picture work and my workflow is mainly digital.
