I looked around in the internet and I got the following system:

Intel Q6600 4x2.5 Ghz
2x2GB DDR2 800
Nvidia 8800GT(S?) with 768MB videomem, 364bit
250GB HD SATA

and I come up to 780 EUR nice deal I think.
In April I will buy that system.

By the way the Mainboard has an Nvidia SLI chipset, so I could use 2 of the Graphic cards in it. I only hope, that Maya works fine with that graphics card...

Furthermore I want to buy a 22inches LCD display...
