MSI GeForce 6600GT PCIe Graphics Card
 

After seeing MSI's unique cooling solution, I expected the NX6600GT-TD128E to have some overclocking potential. Fortunately, I was left impressed, with the card reaching a maximum stable core speed of 565MHz and maximum stable memory speed of 1.115GHz. This was a 13MHz core increase over Albatron's GPU overclock, but at the same time a 5MHz decrease in memory speed over the card.
