My Korean monitor just died so I grabbed a Dell P2715Q 4k monitor. My current video card is a GTX690. I was planning on building a new rig next year when the next iteration of chips from nVidia and Intel arrive. For now it looks like my choices are: 1. Keep my single GTX690 2. Add a second GTX690 3. Get two 980's in SLI 4. Get a Titan X Adding a second GTX690 (~$300) is within my budget but I really don't want to drop $1k plus on video cards at present. Will a second GTX690 do me any good or should I just play at lower res / settings until I build a new rig next year?
