Buying new gaming pc

[Drill]

Hi! Im going to be going off of the guidelines to explain my situation

1. Budget & Location

I am buying a new pc for this summer. I have saved up a total of $2,000 USD. I wouldn't like to use all of it, but if I have to I will. I live in North Eastern United States. Climate is cold winters and warm summers. 

2. Aim

I will be using this pc for gaming and school work, and I do plan on bringing this computer to college with me. I don't plan on really playing AAA titles. Probably CS:GO, Osu and Overwatch. I would like to run them at higher frames then I have now so I can use a 240hz monitor. Right now I'm using a computer I built a few years back with a GTX 1070 founders and i5 and it runs all games well enough for my current 140hz monitor.

3. Monitors

I right now have and will be using two 27in curved Samsung monitors running at 1920x1080 60hz. Also one 27in 140hz Asus monitor running at 1920x1080. I plan on upgrading the Asus monitor to another monitor that runs 240hz.

4. Peripherals

I do not need to purchase any peripherals. I will be using a wired connection so I WiFi card is not a necessity but would be ideal. I already have a Black widow v2 and a Razer hyperflux. I would like to use any Windows 10 edition.

5. Why are you upgrading?

I am planning to upgrade because my PC is a couple years old, it's not running as fast as it used to. I am also planning to upgrade to a 240hz monitor so I would like a pc that can keep up with that.

 

Thanks

You won't see that much improvement in buying a whole new computer. You already have a good gaming computer so the only thing I'd upgrade would be the GPU. Your PC is running slower because you have been using it for years and probably didn't reinstall windows in all this time. Do a complete reinstall of windows and you'll find that your pc is just as fast as it was when you bought it. 

Also could you please write the whole specs of your current PC.

Yes, my build right now has a GTX 1070 founders EVGA Edition, i5 5500k, some weird msi motherboard, Corsair water cooling, case is a mid tower kinda ugly, 250 GB SSD, 2 TB HHD. If I were to replace the graphics card, what should I replace with?

 

Brob I will definitely consider that build tysm

And if I were to upgrade my GPU, wouldn't my CPU bottleneck it?
