don't get that block...those full blocks are a waste. The memory doesn't need to be water cooled as it doesn't even come close to getting hot. Some regular VGA ramsinks is more than adequate if you want to add something. All that block will do is take performance away from the GPU being able to be cooled.
Do you have the bigwater or something? Is that why you've got 1/4" tubing?
I had the bigwater before...it's a joke so I wound up just taking it off and building a real system and the difference is quite astounding.
Weak pump, tubing is ridiculous, buuut yeah...so really you should just consider saving up and building a real syste, but altogether, simply put you don't want that kind of GPU block especially on a weak system although I wouldn't ever recommend it even with a powerful system.
if only you really were orihime....................
