evga has its own oc utility along with a stress test. no need to use afterburner.
btw the lifetime warranty only applies if you register your card withing 30 days. then again, when it comes to lifetime warranty, most card will last you longer than you will need them. i have a 9800gtx+ with life time warranty ended up giving it away, couldnt wait for it to get damaged to upgrade to a evga 465 again with a lifetime warranty.
lifetime is nice to have, but doesnt mean you will every use it. then again, who knows, the extra 20 bucks you pay for the lifetime might be worth more than the 50 or 60 bucks you pay at best buy on top of it.
