Also people were saying to look into HD5750/5770's as an upgrade, I have been looking around and they seem to mostly only use 1 6-pin and include the converter, and they don't seem to use as much power (based on reviews). How about something like this?

I'm not looking to run Ultra by any means, but currently I play at 1440x900 and have everything at low and I would like at least a little bit of "prettiness" with still nice FPS.
