Please help me with my doubt!

Hello,
First I will give you the info-

My system specs---
# A GA-M61PME-S2P motherboard
# 4 GB DDR2 RAM 800 MHz
# An AMD Athlon 2 X2 245 CPU
# A Corsair CX 430 W PSU
This is my PSU.....

# LG Monitor with max 1400 X 900 resolution.

Now the question is if my PSU will handle an hd 6670 or not.Will I be able to run games like ACB, Dirt 3 and Crysis 2 maxed out without overclocking?
Any help will be greatly appreciated!
