Hi all, I'm in need of a powerful workstation. I will use it mainly for number crunching (Computational fluid dynamics and genetic algorithms) and CAD, it will be my main system as well. I will run mainly Ubuntu as my OS but I need Windows for CAD so I was thinking about dual booting. Since I'm on a low budget (<700/800 Euros) I was thinking about buying a refurbished HP workstation, I've been scanning ebay for quite a while now, there are a lot of HPZ600 Dual XEON out there but what really got me interested is this: - DUAL CPU XEON X5670 (2,93 GHz - 3.33 MAX) - 24 GB ECC DD3 RAM - 1 HDD 1 TB SATA 3.5" - AMD FirePro V7900 2 GB VRAM - WIN 10 PRO pre installed. All of this for less then 600 Euros, it come with a 1 year warranty for everything but the graphic card which is given a 3 years warranty from AMD (so it seems the GPU is brand new). This seems to me a pretty sweet deal, Am I missing something? The Z series has a solid reputation and this workstation seems to have pretty solid spec, the CPU is still relevant today (and there are 2 of them), enough RAM and a more then decent new professional graphic card. What do you think?
