Just a heads up for anyone who is actually getting no joy from their etailer...
I bought a Panasonic projector a few years back and after it continually failed due to overheating issues I asked for a refund 11 months in to my 12 month warranty.
The etailer said no - Panasonic said no.
I filed a small claims court against the etailer (no other option) - got paid full amount immediately without having to go to court.

I am happy to do the same again if I don't get offered an exchange or refund.
Don't be put off by all these arm chair bandits who think Nvidia should get away with this.
