Does anyone know how long the graphics card warranties last from the following manufacturers?

MSI
Gigabyte
ASUS

EVGA
Zotac
PNY

KFA2

I've just searched on the MSI site, Gigabyte site and ASUS site - first two have a link to warranty info (but won't give a number of years) and ASUS bury the page deep in their support area (and then still don't give a number of years). I have a feeling it will be a similar story for the rest. How are we meant to know who will offer good (3 year+) warranties?

There seems to be a lot of knowledge/experience on here about which manufacturers offer good after-sales support etc, though I think a lot of that is US-based - the same service may not be offered here. I've sent off some emails and will post results back here if/when I get them.
