What is a good motherboard that would work with intel core i5-2500 sandy bridge 3.3ghz?

Well, it depends on your needs. It has to have LGA 1155 CPU socket. Which chipset you choose for it depends on what you want out of the computer - the most common are H61, H67, P67, and Z68. Go ahead and look up the differences.

Other than that, there is SLI and/or CrossFireX on some boards, some boards don't have integrated graphics so you'll have to get a discrete graphics card for it to work, some of them have different interface types like PATA and Firewire.

Read reviews and figure out what you need the board to have on it and get one that suits your needs, is reliable, and is within your budget.
