GTX 480 refurb questions.

[Adster3000]

Does anybody know whether OCing one of these will void its 1 year warranty?
I'm not gonna touch it if it does.

Also, Is it worth OCing it? I read a fair bit about other Nvidia cards being "good overclockers" and having decent performance jumps, like eqivalent to the next card in its series (e.g. 460 overclocking to 470 standards, this is just an example, unsure if it is exactly the case.)
I understand that the 480 already runs pretty hot, I am unsure what is too hot for it (or anything Nvidia) and have no idea whether it's close to that already or not.

And finally, if you think it is worth doing, could you point me towards a guide on how to OC Nvidia cards, as I was previously on ATI and I'm not sure if it's much different.

Cheers.

Software overclocking will not void a warranty. Removing the cooler/modifying the card will. (With the exception of bios modding, if it can't be changed back because the card has blown)

I have a 480 overclocked to 840 on the core, which is about 580 performance. Although no games that i play tax the 480 at stock speeds, so it's not really worth it. Overclocking is standard for me

Note I was overclocking with the stock cooler, but the noise and heat started too annoy me, so banged a gelid icy vision on there.

Although for reference, I wish I had bought the zalman v3000f. I experienced one on a 470 a few weeks ago in a build and the thing is phenominal.

MSI afterburner is the best peice of GPU overclocking I find, aim for about 820 on the core. You don't really wanna be messing with the voltage on stock cooling

Thanks for the information. I would buy an aftermarket cooler for it but they're just way too expensive.

What about shader clock? This new to me.
