I currently have a watercooled rig that I bought off a forum member a couple of years back. It has very thin tygon tubing which looks great I have to say.

I am about to upgrade the gfx card which has come with a cooler with 1/2" fittings and wondered whether it was worth changing the whole system over - is there any advantage to a smaller or larger bore tube?
 
Sounds like you are about to install the graphics cards Ian! What components are in the rest of your water cooling system?

Edit: This site is very useful and there is a flow rate calculator (Excel spread sheet with autocalculation) you can download (top left on main page)

11/8mm can tolerate a much tighter bending radius than 1/2", so you can connect blocks together using a shorter length of tubing. 1/2" offers slightly lower resistance to flow, so per meter 1/2" performs better.

Both effects are thoroughly negligible, and to some extent cancel each other out. I use 11/8mm tygon.

Its an aquacomputer system - with a pump, a res, a cpu block and, currently, an 8800gtx vga block - really thats all i know - forgot the spec long ago - lol
 
Nothing wrong with aquacomputer - good german company
I'm guessing it was one of the larger Eheim pumps.
Post a pic and we can all play guess the WC kit :D

I'll stick with the small bore tube - as you say it looks good, kink resistant and has a proven track record with the Aquacomputer hardware. AquaC's new(ish) plug&cool-connectors take all the hassle out of building a loop. Well worth the few quid for a full set and some new matching tube.
