I know there has been more than a few instances where people here have discussed this card, apparently with regard to low price and power consumption. Newegg is having a shell shocker deal on it today so figured I'd pass that along.

IMO the 550ti will be faster for CUDA. If you're not playing any games I'd recommend that instead.

...although the power consumption is significantly higher.
