I was not going to "Do water cooling this time"
But I'm running 24x3 monitors and want to span a game across all 3 using eye infinity, i don't think nvidia card can do that yet.
I'm going to look at the quality of the 6990 when they turn up and look then decide who to do. Either get two 6990 or maybe 3 6970s what works out faster.
However this will get warm, so water cooling looks like a must. What rads will fit in the top of a HAF x and will it be big enough to cool the cards, I've an H70 on the sandy bridge so I'm may just run to separate systems.
I know i have to swap out the MB asus look like I could swap it with them for an upgrade. For the sabre-toothe or the maxiums extreme 4. Is it worth doing the MB as well?
