Best mobo for overclocking, with my current CPU+RAM

Hello everyone! I am in need of a new motherboard. Here are my components that I need to move over to it:

AMD Phenom 9600 Agena 2.3GHz 4 x 512KB L2 Cache 2MB L3 Cache Socket AM2+ 95W

CORSAIR Dominator 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit

NVIDIA 9800GTX+

Ideally, I want something that can handle some basic overclocking, but nothing that's more expensive than $140. Thanks in advance for your help! Let me know if you have any other questions...
