I would agree, reference coolers expelling heat to the rear of the case are best for air-based SLI.

Yes 1440p but with a 120Hz monitor so would like to achieve 100+ fps almost all the time. That happens to a large extent with 2-way SLI but there are some games (Crysis 3) which on highest settings will not achieve 100+ fps consistently with 2 780s.

I bought a refurbed Alienware M17x R3 for around £500 (2670QM and GTX560M) a year ago. Then recently separately bought a 2960XM and GTX780M and plonked them in. Upgrade cost around £650. It now has around 3 times the frame rates in games. The alienwares are good quality pieces of kit. Working in the M17x was fairly easy.

Also loving my SLI GTX780 setup. I have a 780 classi to go into the rig for tri-SLI but not sure it is even really needed for 1440p.
