CPU + Mosfets or CPU + GFX under water?

[Nem]

I've just bought (so already have these parts) the Asus Rampage II Extreme, Core i7 920 DO, Asus Ati 5870, + the rest of the system.

I've got the Swiftec GTZ SE block for the CPU, along with the Swiftec pump, and XSPC RX360 radiator.

I've also got the EK mosfet water blocks for the motherboard, but am wanting the GFX card water cooled as well. Am I best leaving the mosfet blocks out all together and just going for CPU and GFX with the parts above? Would adding the GFX block to the CPU and Mosfets compromise the temperatures too much.

Obviously this should have been asked before buying the parts, but it's done now

Any suggestions would be great. Also I've not got budget for a second loop for the gfx card alone.

Cheers

Nick

with gaming ..all(in one loop) of those shouldn't be a problem if you have fans..and decent ambients..and your oc'd i920 isn't pushed too hard
