is the Sapphire 6850 toxic reference?

well i just wanted to know if the Sapphire HD6850 Toxic was a reference design card or non reference design card.

i ask because i have heard and seen a few things on the internet that say different things and i would also like to purchase a water block for my card but i now unsure what type i need to buy

Im pretty sure its non reference.EK web site shows it takes ver2 waterblock.

maybe it might be time to upgrade to two cards i can get waterblocks for then.

i was running two 6850 in crossfire untill one stopped working which could have been because of heat issues as there is only one slot gap between them.

anyone got any tips or veiws on what i should go for? im running a P67 board so as far as i know i can use nvidia or amd/ati
