Threw this together. Went with a blue theme, you can change out the black/blue case for a solid black one if you wanted. Has 16gb ram, can upgrade to 32gb in the future if you want for whatever reason. Solid cheap gpu, might even be overkill if you don't game? You could get a cheaper/lower-end one of you really wanted probably, but overall it will more than provide for your needs. With the GPU and CPU I'd check your monitor compatibility to see if you may need an adapter. Can potentially fit 4 monitors. I went with the i7 4790, it has hyperthreading which would help if you have a lot of processes running (make things smoother). I added it because I had some room from the $1000 budget. You could downgrade to the i5 4690 if you wanted to save ~$90. Gave you a 250gb ssd for fast bootup/whatever else, and a 2tb hdd. If you think 2tb is too much, the 1tb version is like $15 less.
