ok I'm on a tight budget and have been researching into great stable easy to use motherboards on a budget. I have come down to two motherboards. The first is the EPoX 8k3a which I've heard alot about and the other one is the ECS k7s5a which I've heard even more about. Any feedback about these boards would be great. Oh and what does raid do and is it worth spendin a few extra bucks for?
