The Golden Sample series are excellent cards, they use the highest quality memory available on a 6 layer PCB.
Due to the memory and PCB combination they can run stable at higher Core/Clk speeds than most other manufacturers cards.
Motherboards based on Intel's 850 chipset are usually manufactured with this type of PCB. <quality stuff>
Nvidea was upset with Gainward when they released the Golden Sample GF2 MX-400 series because they performed almost as well as the GF2 GTS/Pro series.
I O/C the hell out of my Gainward GF2 MX-400 and it has never given me a problem.
When I bought the card it was set at 200/166, I hacked the cards BIOS and am running it at 225/350. <core/mem>
Gainward also includes a great software bundle, Cyberlink Power DVD, Power VCR, and several other nice programs came with mine. <3 disks>
