Is there any ways I can upgrade my gpu on this machine to a newer GTX 970 MSI? Coz the old Quadro k2000 is running slow and I don't wanna spend another 100+ bucks on a old used Quadro k4000 or k5000, so I'm considering a GTX 970 which is much cheaper and giving higher performance. However, Im worried that it cant support by new gpu, so by any chance will it not boot if I install the new gpu?
