Hi, I am trying to get a good 3D modelling PC for use with maya, I won't be doing anything really intense, but I need pretty good performance. but i'm on a budget. so i was thinking, what if i just add a workstation GPU, to my current computer, which has an amd athlon 64x2 4000+ cpu, which is a 2.1 ghz dual core, and an acer f690GVM mobo, which is pci, it also has 4 gigs of ddr2 ram, and a msi geforce 210. so what if i just replaced the 210 with something like an nvidia quadro 2000??? would that be good enough? or would i have to build a new PC?
