Regarding warranty, we haven't mentioned it and (quite surprisingly) no one has asked about it. The warranty period will be 90 days from the date of delivery.
@chup,
I think 90 days are not enough to obey EU laws for planned EU:EU sales process.
On the other hand, from buyers perspective it may make sense to get in touch with Xilinx EU distributors, there are some sales contacts in EU I remember(Italy and France). Those would have to provide 2 yr warranty.
I don't try to put anyone down here don't get me wrong. You seem legit, I am just that voice of doubt in the back of peoples heads 
Although I am sure most will ignore me lol.
Indeed. I would be really upset even if a $500 GPU fails, not to mention a $3.5K-5K card. Although I am sure most will ignore me lol.@senseless, does this 90 day warranty apply to modified FPGAs only (due to modification) or to out-of-the box (unmodified) ones as well?

I know there are issues in the United States with 90 day warranties too, one of the main reason you couldnt order Mining Cards from distributors and major brands/stores.
The warranty applies to all cards shipped.

A 90 day warranty for anything that will be beat to death as mining hardware is more than reasonable.
