Need suggestions for light gaming, cad, 3ds max & photoshop station.

Current Setup:

-i7-3770K 3.5GHz -Gigabyte Radeon HD 7950 3GB -16 GB DD3 Ram

Like I mentioned. I do some light gaming, mainly BF1, so although I'm intrigued by 144hz I don't think it's crucial.

I believe Ultrawide is the way to go for my usual activities. I use a dual monitor setup at work and I love it, but doesn't make too much sense for the light gaming that I do, plus I have a laptop open right next to me almost always. The 144hz Ultrawides look appealing, but I don't know if my current setup would be able to handle it, not to mention out of my budget.

Budget is not set in stone, but ~$600-800.

Thanks!
