The mcr 220 is a 240 rad.
I can't help you regarding the mcr320, but i have 2 mcr220's in a single loop with a cpu & gpu block. I'm using the laying mcp355 with petrastop with an apogee cpu block & mcw60 gpu block. Cpu @ 4ghz & gpu never go above 40.
If you have space issues opt for the mcr220 stackable that swiftech will be releasing anytime soon. If not, just add the mcr320 to your curretn loop & when you have more money get another pump for the mcr220 & add your gpu to the loop.
