A third 6950 or watercool my current cards?

Hey guys,

I currently have a Koolance WC setup (see sig) and was thinking about watercooling my two 6950s (I have them OC'd and unlocked). However, I was thinking of adding a third card instead. A third card would be about 30 - 40 bucks cheaper than WC'ing my two current cards.

I wanted to get some opinions on the performance increase that a third card would give me, over lowering the noise of my current GPU fans with watercooling.

I know I could have Googled some info, but wanted to get some opinions from the [H] group!

I can't comment on adding a third card from experience but I've just added EK waterblocks to my pair of 6950's.

I put them on their own separate loop using half of a twin dualbay res with a Laing DDC pump for each loop. The gpus have a 360 rad and the cpu has the other loop with a 140 rad.

It's bloody hard work and quite expensive but the gains are enormous. Neither of my cards gets to 50c now and the whole system is practically silent.
