Which one of these 2 is better?

[WaterFlex]

Hello guys Just`ve bought AMD 7970 graphic card and now i`m thinking about watercooling.

Which one of these EK waterblocks is better?
The old one:
EK-FC7970 - Acetal+EN (Nickel)

or the new

EK-FC7970 - Acetal + Nickel CSQ

Thanks in advance

EK-FC7970 DCII - Acetal (Non Nickle Plated) Would be my preference.

and what if one already bought 2 'reference' cards? buy DC2 blocks and send them t milling shop?

Actually I'm having second doubt as well. I was even considering swiftech universal block Swiftech MCW82 with heatsink for 7970 but that's like 97$ so you could probably buy better complete block for even less money so reading on I bumped up bundymania's 7970 block review I don't think Koolance is much appealing but price and performance... makes me thing again. It's really interesting read though, not sure if you're only limited with those two EK produc, but it's worth to consider. Hope it helps.

if one is "card swapper" universal block with unisink is better idea IMHO - no need to add to each next card $100-150 for FC block (only $30-35 for unisink/mounts ). and if this setup for "long time run" - FC block has _slight_ advantage - easy to make CF setup with all that parallel/serial bridges etc. ... each has pros and cons and really depends from local airflow, loop aesthetics and such
