If you just want to spend $1000 on video cards alone and have the $500-$1000 for a higher resolution monitor then go for it.
This is a great start. I did not include a case or an OS. The case is something you will have to look at everyday so you need to pick it.
For 1920 x 1080. A very solid build.

Now here are the higher resolution monitors. Obviously you get what you pay for.

If you can afford a higher resolution monitor and budget is not an issue then add another ( identical ) GTX 780 to my build above and change the power supply to this.
