So I have got a HP Z600 workstation as a hand me down, I get it next week. Its a dual xeon set up, both quad core, 12 GB of ram. From what I believe it has a 650 watt bronze power supply in it but it only has a six pin PCI power connecter. What I would like to know what GPU I could put into this just to give it a purpose a the spare pc, of for my mates who come over. Only games we play aren't CPU intensive so it all should be fine. Then the fact I do a lot of things on 3ds Max and Maya despite this machines age, it should render a lot better than my i5 with a 1070. All I really want to know is if somebody has one of these machines and put decent graphics cards in them. I would like to get it sorted before I receive the z600.
