Hello, how are you? I am currently looking for a workstation. The main usage is photography work (Lightroom and Photoshop). I was looking at a 2009 8 core Nehalem Mac Pro to use and upgrade as time goes... The plan was to get the Mac and a pcie Plextor M6E ssd. Than as time goes, get a better gpu (Comes with 5770), more ram (comes with 16gb) and finally upgrade the cpus to westmere 6 cores (X5675 or x5690). But this is expensive! The base mac alone I am looking at 700 euros and it is a 2009 machine (I know, Macs are expensive.) On the flip side, I saw a used HP Z600 workstation for sale locally. It has two X5675 cpus and comes with 24gb of ECC ram. The GPu is a weak nvs300 but can be easly upgraded. The best is the price. It is only 400... I don't know if I am thinking wrong, but the HP already has a pair of beefy 6 cores processors and a good amount of ram and costs almost half of the mac pro. Why would the Mac Pro be a better buy? Cheers!
