Computer specs recommended for 3D modelling and rendering

Hi i would recommend you is instead of 750 gb HDD take 1 tb HDD rest is fine according to me

Wow, all I have is a dual core i3 (3.3GHz), intel gma graphics, 3 gb ram, windows 7 64 bit and 500gb hdd. It's really not great for 3d work. :(

3gb ram is not enough for render. At least 8 gb ram 1 gb screencard and i5 processor

I have:
Processor - AMD FX 6300 six Core 3,5GHz
Memory - 4gb 1600MHz DDR 3
HD - 500Gb
Graphic - Asus GT 630 2Gb
OS - Windows 7 64bit

This is much better configuration than my old PC, only what I need is more RAM, at least 4GB more.

firdz3d you have nice machine :-)

Yes 8gb is better

I think the only important part here is the processor xD I know because I have two computers, one of the them very old. I can model the same, but the time of render is the great difference.

hmm, I guess since it is the discussion topic... Here is my build specs:

intel Core i7 Processor
16gb Ram
nvidia GTX570 GPU 1.5 GB
Windows 7 64 bit
1tb seagate HDD

I love my gpu, but I would like something better that is made by nvidia if possible. the GTX580 yields hardly different results, for double the price. :/
