Here's how I do it, and I've made more than a few cabinets. Cut your sheet goods with a circular saw, but don't try to be accurate, make the parts an inch or so oversize. Use the table saw to trim them to finished size, and that's best done using a panel cutting jig that sits atop the table; you put the part to be cut on the jig and the jig and part both go across the saw top; perfect cuts everytime. A fancy table saw or $400 fence is not required; my saw is a $200 Sears, and my panel cutting jig I made from a 2x3 foot piece of plywood and some scrap wood. This picture shows the jig on top of my saw.
