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?
Yeah, that's a pretty slow PC by workstation standards. I would build an entirely new pc. You should get a Xeon or 3770k (depending on if you overclock, price and what memory you intend to use), 16GB of memory and AT LEAST a Quadro 2000 or Firepro v5900. I recommend the Firepro as its faster in Maya than the Quadro.
It's just for modeling than it doesn't really use the cpu at all. The graphics card is holding you back and a quadro would help significantly for viewport performance. As long as it's not too complex, 4gb ram should be enough. I used to work on an old c2d 2.1ghz with 4gb ram, now has a 6570 and can handle upwards of 100k polys. It's the textures that will fill the ram otherwise I'm sure it'll handle more polys.
how about an fx-6100 or an fx-8120??? i hear the 8150 is almost as good as the 2500k, which is more than good enough for me. or maybe something like an a10-5800k. would one of those cpu's + 8 gigs of ram and a firepro v5900 do fine?
