WELL the REAL answer is YES ... Sapphire's OFFICIAL statement is it WILL VOID your Warranty ... it falls under the "physically modified by customer ... products become non-functional due to customer improper use". However as others have mentioned, who's going to know ? first off DO NOT OverDO your OC and your card should be fine, second off IF you do develop problems with it, return it to defualt settings before you send it off to RMA ... and even though " OFFICIALLY " Sapphire has the disclaimer in their warranty ... they are a good company and as long as you didn't completely go out of your way and fry your card they should warranty it.
OFFICIAL WARRANTY = http://www.sapphiretech.com/presentation/support/?cid=3&psn=000203&lid=1
Additionally read on Sapphire's VGA forums ... http://www.vgaforum.com/?psn=000205&lid=1 ... they can't even TALK about OverClocking on that forum.
Don't Post anything to do with :
Voltage Modding, Wire modding, BIOS modding etc. This is a request from Sapphire, as they receive lots of RMA's that have been the victims of bad modding, overzealous clocking etc. Please refrain from posting up things like this, as it's potentially a card killer for people who don't know what they're doing etc.
Don't forget - ANY modding of the cards will result in a VOID WARRANTY.

i cant remember on told my head, but its around there. i havent oc mine since i first got it, never need to cause the card just so fast without it.
He should be able to OC safely to at least reach HD-6970 performance levels ... which is 880 MHz core / 1375 MHz memory ... and 1536 Shaders IF his card UNLOCKS.
The Dirt3 Cards stock voltage is 1.1v and I think software capped somehow at "1.18v" ... since you're concerned about the warranty issues, I wouldn't mess with upping the voltage, and thus your OC's will most likely not get much above those 880/1375/1536 specs. That card really isn't designed to push it much further than that anyways so keep it in the pocket and you should be good for several years of service.
