Budget PC for 3d moddeling


Sep 20, 2011
Hello all!
I trying to build budget PC for 3d modeling.
Price should be as low as possible up to 500$

I already bought dell precision 690 motherboard
( 2 socket LGA771, up to 32Gb of DDR2 memory (possible to buy memory riser (it's worth near 10$) , so up to 64Gb with 1Kw chasis), 3 PCI-e x8 slot wired as x4, 1 PCI-e x16 (hear about possibility to add one more with video riser)
, 2 Intel Xeon E5320
(4 cores, 1.88 GHz ea. (planning to overlock to 2.33 GHz ea.) 8mb L2 cache ea. 1066 MHz ea. ).
and two 2X1GB PC2-4200 DDR2 533 PC4200 ECC RAM. It worth near 150$. Planning to buy 1Kw power supply, and 16 Gb of memory.I already have old DVD rom, and want to buy some cheap HDD ~ 60Gb for Windows and 3Ds max only.

So my question is: please tell me what videocard to choose (I thinking about quadro FX4600), tell me more about that video riser and rate my build for this money please.

Thank you.
