The advantage the ECS has over what you are using is ddr and the ECS will take up a 2600+ 266 cpu. The ECS you mention I believe has usb2 support also. I have both boards (ECS K7S5A non pro, Soyo K7VTA) in a couple of my older computers, and they have been good (basic) main boards. It depends I guess, on what you are wanting to do with your computer. I have an AMD 2100+, 768 meg pc100 in the SOYO and an AMD 1700+, 512 meg pc2100 on the ECS, I cannot tell much difference between them. I would give the advantage in this case to the ECS.
