quadro fx 3800 vs quadro 4000

[adit1001]

Hi

I want to upgrade my actual video card Quadro FX 3800, with Quadro 4000 or maybe Ati FirePro V7800, but I am not sure which is better. I am interested in improving my viewport speed in 3d max, when working with high polycount. I read that the new Quadro video cards based on FERMI are very fast(5x faster as the old ones), maybe someone tested them. Any advice would be helpful

Thanks
