Currently have a 780 Ti (MSi Twin Frozr), and that's where I'll stay until I finish school and/or get a better job.
Also, would like to hold out for a card that can run smoothly with a 4K or 21:9 1440p display using G-Sync or DisplayPort 1.2a.
Switching gears from the other commenters (who are understandably interested in high-end socketable chips), I'm glad to see that the Broadwell U-series chips are launching in a few months. I'm thinking about getting a new laptop this year; hopefully Broadwell can improve further on the energy...
