I just talked to BFG and they state that as long as the product. ..

>> Was not damaged while being installed.
>> Was not damaged by software or hardware from a company or individual other than BFG Technologies or by motherboard incompatibility.
>> Was operated in accordance with BFG Technologies specifications, instructions and any technical support directions.
>> Was not modified or damaged by overclocking, tampering, user error, accident, disaster, abuse, misuse, power supply, power application, alteration, repair, modification, a fix or replacement by someone other than BFG Technologies.
You should be o.k.
I found that strange as warranty is what I do for a living (warranty underwriting, not service). Normally sales through "gray market" resellers cause the warranty to be null and void. Contact them for further confirmation on their warranty policy if necessary.

P.S. Your biggest concern should be if this card was *EVER* overclocked, this does void your warranty. They are very up front about that.
