need you opinion please

[\/\/ater (ooler]

this is my first post, so hi all

this will be my second water cooled rig and here is the parts i have:
2x Swiftech MCR320 radiator
2x Swiftech MCP-655 without the controler
1x D-tek Fuzion CPU water block
2x EK-MultiOption res 150 Rev. 2
6x Scythe Ultra Kaze 3000rpm with Zalman ZM-MFC1 Plus Fan Controller

all will be 1/2" tubing and the coolant is FluidXP+Ultra (Blood Red)

and i will be cooling:
EVGA 780i (when they come up with a NB block) i still didn't order it yet
Intel E8500 (didn't order it yet) or a QX6800
2x 8800 Ultra (i might get a third card or wait for the 9800GTX) i didnt order the blocks yet until i decide
my case: Lian Li v2000

so im doing two loops, my question is will the MCR320 will be able to cool a e8500 highly overclocked and a NB and SB, or a QX6800 also overclocked with the NB and SB?
the other loop will be for the GPU.

so please give me your opinion
thanks
