A friend of mine is using this config in Bangalore for his 3d workstation
Core 2 Quad Q6600 with Cooler Master Hyper TX2 CPU Cooler
Asus Striker extreme motherboard ( he wasted money on this

, this is of no use to him)
Quadro FX 1500 with 256 MB DDR3 RAM
2 GB Corsair Value Select RAM
It works fine for Maya, zBrush etc, he is into charectar modeling only.
I use my workstation as
Core 2 Duo E6550 with Cooler Master X Dreme 775+ CPU cooler
2 GB Kingston ValueRAM
Sapphire Radeon 3650 softmoded to FireGL
Intel DG31PR motherboard (Solid buy)
Look for something similar, today Core 2 Duo E8xx series is out so look at hte config i gave above. You might want to change the Motherboard if u intend to overclock but I don't recommend overclocking on a workstation.
