Help me build a $1000 PC that will outperform my current one

[kilerquin]

So around 2 years ago, I bought this prebuilt PC for around $1300 I think it was. Here are the specs:
CPU: i7-4790 @ 3.60GHz
GPU: R9 270
RAM: 24GB
Storage: 2TB HDD and 256GB SSD

Only this past month have I realized how bad of an investment it was, so I am planning to sell the parts and build a new gaming PC... except I don't know how to build a PC. I was hoping if someone here could suggest a build for me. My budget is $1000 and I want it to be more powerful than my current PC. This budget does not include my monitor because I am buying a new one soon anyways. I'd like at least a 256 GB SSD in the build as well since I prefer SSD over HDD. If I should include more specs or if I should keep any parts from my current PC, please tell me. Thanks in advance to anybody who responds!

Hones;ty, that's not really a bad investment. The only thing I would change is the GPU. You could possibly upgraded to a 4790K, but I don't think an extra boost clock would matter. Also, it depends on your motherboard. Keep the hard drive and SSD (or add another one) and just upgrade the GPU. You have enough RAM and you still have 4 cores and 8 threads. Again keep the build and call it a day.

You could also think about a GTX 1080 Ti, but that depends on the monitor you are getting. If it is not 4K, then it's probably over kill. That GTX 1080 should be able to handle any game at 1440p.

Thanks for the advice! I'm getting a 144hz monitor to play CS:GO on, staying at 1080p. What GPU should I get to be able to play CSGO max settings at 144 fps?

You can get the GTX 1070, but it's a bit overpriced (as many GPUs), so the GTX 1080 will be the best value right now. The listing I have above should work just fine.
