Hello and welcome to the forums,
 
Second hand owners only get a 3 year warranty on select products which starts from the date the product shipped out of our warehouse. 
 
You do not need to register the product yourself first. Please see http://asia.evga.com/support/warranty/ for the warranty terms in your area, if the seller is in a different region they will need to see their region's warranty terms to be aware of their available warranty. 

Correct. 
Transferable Limited Warranty (Second-Hand Purchasers)


The length of the Transferable Limited Warranty is determined by Product according to the suffix associated with each Product's identification number as set forth below and will be measured beginning from Product's original date of shipment from EVGA or an Authorized Reseller:
3 Year Transferable Limited Warranty Product Suffixes: -K0, -K1, -K2, -K3, -K4, -K5, -K6, -K7, -K8, -K9, -KR, -KB, -KA, -KF, -GR, -SR, -V0, -V1, -V2, -V3, -V4, -V5, -V6, -V7, -V8, -V9, -VR, -Y0, -Y1, -Y2, -Y3, -Y4, -Y5, -Y6, -Y7, -Y8, -Y9, -X0, -X1, -X2, -X3, -X4, -X5, -X6, -X7, -X8, -X9, -XR
2 Year Transferable Limited Warranty Product Suffixes: -L0, -L1, -L2, -L3, -L4, -L5, -L6, -L7, -L8, -L9 -LR
Products described by the following suffixes are not covered by the Transferable Limited Warranty: -B1, -BR, -BX, -DR, -RX, -RB

As you can see in the above post if the part number ends in -X1 there is a 3 year transferable warranty.
