I'm wondering what people think the best AMD motherboard (standard, not micro) would be on a budget. I know a lot about intel motherboards, but I'm afraid I know little about AMD and the various chipsets.
Motherboard must be under $100.. more concerned with stability than performance. No ocing. For use with this processor: Newegg.com - AMD Athlon 64 X2 4800+ Brisbane 2.5GHz 2 x 512KB L2 Cache Socket AM2 65W Dual-Core Processor - Retail

Are you going to be using SLI or Crossfire?

Nope.

This one Newegg.com - GIGABYTE GA-MA770-DS3 AM2+/AM2 AMD 770 ATX All Solid Capacitor AMD Motherboard - Retail
just a couple dollars over $100 but its supposed to be very good. Gigabyte makes excellent boards, im considering using it for my own Phenom build at some point.
