Well, with out going to much indepth the ECS K7S5A is one of the best boards out there for the money. If you are on an extreme budget, it is the best choice. I think it retails for around 70-80 bucks right now. Where you got it for free it may be worth replacing your FIC with it. You may get a little bit more speed out of the chipset. The SIS735 got very good reviews when it was first released. You should do a search on Google for some reviews on the board. I think you'll be a bit surprised when you read what people are saying about it.
