- what are your needs vs. $, kinda answers this.

All switching is done in layer2!
Layer3 switch 'features' (functionality) is was the vendor put in the
box. Depending on the amount of $ you're going to spent, you can have
switches that can act as routers.

The mpps is normally what the switch can do in total / back-plan
back-bone or whatever the vendor want to call it.

If you're going to calculate a $ pr. port cost-benefit, then you have
to make sure the rest of your setup is balanced accordingly (why spent
time on $ pr. port if the nic in the rest of the setup is cheap)

There's a lot more to network boxes (router, bridge, switch et al.)
than just price and capacity, e.g. management, (I)OS, firmware,
best of luck.
