Nothing wrong, this card comes close to perfection for individuals.
I possde for a year and a half coupled Corsair PC3200 2x512 MB, P4 2.8C, Radeon 9800 Pro, 2x raptor 74go ...
It is perfectly stable (windows xp and mandrake 10 test and provides more than enough connections including a raid sata high quality!
