I am thinking of getting this water cooling kit
http://www.frozencpu.com/products/16891/ex-wat-219/XSPC_Raystorm_750_RS240_Extreme_Universal_CPU_Water_Cooling_Kit_New_Rev_4_Pump_Included_w_Free_Dead-Water.html
And I am asking if: I put a waterblock on my 7870 will the pump be able to handle it, and will I need more Rad. space?
Thanks and any answer would be nice :)
Ps my build is this
