I Currently have a PNY GTX 480 and want to buy another for SLI (XFX 680i LT SLI Mobo). Found one for fair good Deal in Ebay site of my country. The seller tells me there will be a warraty of 1year (this is a new unopened Dell OEM card). Its price is $375 (I am not in US but this is approx. conversion). Should i go for this? Can i believe the seller of 1 year warranty?
