Is it worth it to have a closed loop for just the gfx cards?
I was thinking about how much heat a x-fire setup pumps out would it be worth simply getting a 1U rad and having a loop just for the gfx cards with a energy efficient pump on a very low speed

Pump->Res->RAD->Gfx Card 1->Gfx Card 2->Pump
 
I'm going to be setting up a seperate loop for my Crossfire set up mainly just to maximise the cooling potential as having 3 blocks in a loop isn't the best solution though it is the most compact. Having said that though I had a QX6700, 2x8800GTXs and a pair of PSUs all off one radiator and it didn't make that much of a difference.

You want the res before the pump by the way as it aids with filling and bleeding the loop.

Thanks :)
I was just curios, as the new gfx cards seem to be pumping out more and more heat, running 2,3 or even 4 of them (such as quad sli or x-fire which is supposidly in the works), that would be an insane ammount of heat being passed through the loop.
I do have a Swiftech 2U RAD atm which is more than sufficient for a core2duo on a DFI infinity with a 1950XT but i was thinking more in terms of future proofing my machine
 
I have 2 1950XTX's and an E6700 on the same loop with just a Black Ice Stealth II for a rad'. Clocked at 695 and under full load the cards reach 74 to 75 degrees, the CPU stays a lot lower for some reason. So a loop with just the cards might keep them a bit cooler, although I am considering adding an extra small radiator somewhere..

a single rad between the cpu and the gpus would you out tonnes

that sounds fine dude, but as Jokester said, res before pump :)

I think you meant that a rad between the CPU and GPU would be a good idea?

If so then that is incorrect as the temperature difference in a loop is no more than 0.5c at most at any one point.

i'll have to take your word for that one :)

edit: actually looking at a post Marci didon xtremesystems i see what you mean. having the extra rad would still help, just the placement that matters not :)
