Hello all!

I don't know the best way to handle my problem.
At the moment i multibox with 5-man-teams, mostly for herb farming and mountruns!

My current PC can handle a 3-man-team flawless, but 5 is kinda hard. Especially in Boralus!
Once i am logged in for a while in the open world the FPS become stable and its looking pretty good.
I have all my slaves put on renderscale 0.5 and settings on low.
My main window is running at 60FPS, all other at 25FPS

Now to the part where i need your help!
I want it to be much smoother. And quicker loading screens, atm sometimes they are very very long.
I should be able to walk arount Boralus and every other city at a minimum of 40 fps.
Maybe i will give 8 Character boxing a try in the future, so that should be also possible.

Here ist my current setup, so you guys have an idea about it!

Intel Core i7-4790 CPU @ 4.00GHz
16GB RAM
Nvidia GeForce GTX 960
2x BENQ GL2450 24"

The options that i see are the following:

1 - Sell the current and buy a new very good PC
2 - Buy a mediocre PC in addition and multibox with them both
3 - Upgrade my current PC for multiboxing (i don't know if its that easy)

My budget would be a maximum of 3000€, but i would be happy if its cheaper!

What do you think would be the best way to get there?
The only thing i can think of to improve is getting an SSD for quicker loading screens.
Maybe there are some magical tricks and tips for making my current Computer work faster, i don't know.

Thank you in advance,
Atsu
