I had an i7 2.93 27" imac and the video card finally died. I am considering replacing it with 2010 mac pro 2.6 12 core / 16gb and some sort of 2560 monitor (maybe monoprice). This would cost around $2100. Pros: still one of the fastest on the 64 multi core benchmarks, easy to expand and repair. Cons: no thunderbolt, usb 3, possibly loud fans Or i could buy the 5k mac and upgrade it to a 3tb drive and 16gb of ram for around $2900. Pros: has warranty, great screen, thuderbolt, usb3 Cons: no firewire, cost, no expandability, 1st gen with possible issues I am a causal user but i have a large media library and need a lot of storage. This machine will remain on 24x7 and needs to be able to run a vmware instance of windows too.
