Well, a dual-core AMD processor at 2.8ghz is a little faster than the 2.1ghz tri-core processor while gaming or running other applications. The thing is, if you're doing a few things at once, the tri-core should run smoother than the dual-core. Also, the tri-core is more future proof because applications are currently, and more in the future, will support multi-threading which let's each core process the same application. Most applications and games currently only let one core of the processor work on it at a time, but one core of the tri-core AMD should run games pretty well.
So hopefully I didn't confuse you too much, but a tri-core should serve you well enough, especially if you're on a budget.
