Hello, so I want my pc to be able to better follow demands of games coming out nowadays, I still have my trusty palit Geforce GTX 770 windforce edition in my case and while it is trying it's best it's running games on lowest settings at most at this point. Now I am wondering if it's worth investing 400 euros into a new GPU or if I should save up money for an entirely new system.
I am aiming for a GTX 1070.

Current system details:
CPU: Intel Core i7 3820
GPU: Palit Geforce GTX 770 windforce
RAM: 16gb DDR3 dual channel
Motherboard: MSI X79A-GD45 (8D) (MS-7760)
PSU: Cooler Master B700

If more details are necessary for a helpfull answer I will get them. :)
Thanks in advance!
