Ugh, why doesn't Newegg post how long the warranty is on their product description page?
Anyways I googled a bit and turns out the X1800XT have 3 years warranty according to some review site.
Zipzoomfly has the same video card, but retail stating it has a 2 year warranty. I don't why the X1800XT and X1900XT have different warranty so I am a bit skeptical on the warranty...
Also ZZF has the retail version while Newegg has the OEM version for sale so perhaps there is even less warranty to none on the OEM version.
