Hi,
I, on the other hand, dislike the ECS K75SA boards. I built 2 systems based on the K7S5A. They often have problems with SDRAM memory & losing their bios settings. You had to get the right combination of power supply or memory to get them to run properly. It took weeks of postings to the ECS forums to get things right. I would rather pay a little extra than go through the problems. All manufactures put out lemons, but I think that ECS puts out more than their share.
On the other hand, I have had great experience with Gigabyte & Abit.
