Just picked up one of these bad boys. I know it ain't the top of the line, but newegg had it for $170, which seemed like a pretty good deal. First off, the thing is a freaking brick! I have never seen such a big card. I mean, just look at that thing! The fan looks pretty nifty though. Anyway, I am wondering if anyone has any experience overclocking this card. Would it be recommended? Should I get a new cooling system before overclocking? I keep hearing about an ATI Tool, but I don't really have much experience with this stuff. Thanks for the help.
