Pretty much all new-ish AM3 boards support that processor. Some older ones might need a BIOS upgrade. As 87dtna said, just pick out a motherboard and then check. A good place to find information would be the manufacturer's website or the product box. If you are in a store, just ask a sales associate. It's not hard to upgrade the bios on a motherboard by the way.
Also it would be worth mentioning that some different boards such as AM2/AM2+ boards accept the newest processors. My motherboard, for example, accepts the 1090t.
Back in the day alot of boards had a removable bios chip. Pretty cool feature, even if you killed the BIOS you could get the board makers to send you a new one and your back up and running. Gigabyte has a dual BIOS chips now, helps a little bit.
The two-bios deal essentially has an unlimited amount of backup and restore "cycles," right?
Dont think you could call it cycles. It has two bios chips. One backup and one main. When you update, it only updates the main. If you have a bad flash or the main dies it will boot off the backup chip.
