Currently running a MCR220 for my 8800 GTS 640 (MCW-60), NB and SB on my DFI X38 w/ a D5 pump. Upgrading to a GTX 295 and was going to get the Koolance FC block, then switch my NB and SB to the same loop as my CPU on a PA120.3 w/ a D5.

This would leave me with the MCR220 cooling only the 295. I am running mid speed yates and was wondering if it would be worth it to upgrade from the 220 to a XSPC dual 120? If we're talking 2-3c and no extra performance out of it, it's not worth it to me. Will the 220 be enough?

Oh, side note... going from 7/16" to 3/8" tubing. I know it'll suck getting those over my D5 barbs, but it would save me $100 from having to buy new tops. Do I have to worry about any problems with the tubing splitting/leaking?
