Graphics card with 4GB around 500,-€ ?

[p-kay]

Hi,

I´m going to build a new machine and am wondering which card around 500,-€ with 4GB VRAM would offer the best value

A quick search on Amazon spit out these cards:

http://www.amazon.de/Gigabyte-NVIDIA-Gr ... 400&sr=8-4

http://www.amazon.de/NVIDIA-GeForce-Gra ... 400&sr=8-3

http://www.amazon.de/EVGA-04G-P4-2673-K ... 400&sr=8-2

http://www.amazon.de/Zotac-NVIDIA-GeFor ... 400&sr=8-1

do you have any advice for me which card is best?

PS:
can´t stress that often enough: your software is incredibly AWESOME!!!
