I am upgrading my AMD athalon II x2 245 to an AMD athalon 955. However I only purchased the cpu chip. Do I need to purchase a new heat sync as well? Or can I use the one that is currently on my cpu?

You'll need a new heatsink.
The athlon II came with a decent heatsink for its 65w it used but the PhenomII 955 uses almost twice as much power (125w) and will just overheat

Heres the 65w heatsink. Notice its just a block of finned metal witha fan on it. 65w isnt a lot of heat to dissapate.

and here's the 125w Heatsink. Notice its a much larger block with heatpipes. 125w is quite a bit.

Can you tel us what size case you have? How tall a heatsink you can fit?
