GPU block

Does anyone know the pressure drop vs. flow rate chart for the EK-FC7970 Lightning - Acetal+Nickel? I've been searching, but I couldn't find it anywhere.

I'm planning on buying the RayStorm 750 RX240 WaterCooling Kit or the RayStorm D5 RX240 WaterCooling Kit, so I needed that info to make a call. I will be adding the GPU block and another radiator (120 or 240, not sure yet) to the loop.

I read that the X2O 750 Bayres/Pump (Black) V4 will be enough for most CPU + GPU loops, but I want to make sure that I will have a good flow rate (>= 1 GPM) with it.

If someone with a similar set up could share the experience and ease my worries, I would appreciate it. :)

I highly doubt you will be able to find actual numbers regarding the flow rate, but the 7970 lightning block is a high flow block, and is made to be able to work with weaker pumps as well:

"EK-FC7970 Lightning water block also features a very high flow design therefore it can be easily used in liquid cooling systems using weaker water pumps."

Thank you, scopey86. Well, I kept looking and found nothing, too. That's expect, since it is a really specific GPU block.

Anyway, I really appreciated your help. Thanks!
