VisionTek and ELSA are the same card, made by VisionTek. Very Good Quality. VisionTek made the nVidia Reference Boards. Gainward is arguably the best, as it can overclock slightly higher than others. The ASUS typically gets the highest scores for it's clock speed(only by a tiny amount), but has trouble with the latest drivers so det 11.01s have to be used. LeadTek has AWFUL memory cooling, worse than MSI which does not use heatsinks of any kind on the memory. LeadTek's Ramsinks actually keep the heat on the modules.
