gtx 1080 ti , fx 8350 , 8gb ram
im thinking if the ps5 will have an ryzen 2 cpu and 1080 gpu i shouldnt upgrade pc , am i right?
unless cdpr decides to not suport next gen consoles
Hang on to that GTX 1080. The new Nvidia RTX (Super) and presumably the new AMD RX and RT cards are not a great enough improvement to make any new GPU purchase worth it. GPU's are also overpriced right now, so just wait until they drop prices or NAVI 20's release in 2020, will force the market to do so. That 1080 is probably already enough to run CP77 comfortably so wait until the Graphic Card manufacturers do anything interesting before launch.
For your FX-8350, I'd highly recommend buying a B450 or X470 motherboard with a nice Ryzen 3600/X/3700X. These offer a superb increase in value-performance and will release in just 5 days. A Ryzen 3600 is just $200 dollars and a good B450 MOBO some $100, excluding taxes, and you'll have a CPU that rivals or beats even Intel's finest CPUs. They also have the Zen2 architecture, same as what you'll find in the consoles and I'm pretty sure the consoles will be similar to a 3600, and not top the 3700X.
Otherwise, wait and save up. The remaining $600 can still go towards your purchase of a PS5 and you're prepared to wait the period of time between CP77's release in April 2020 and the PS5's release later that year, if the GPU manufacturers are still playing hardball. You can make any other decision later and you'll have a rig that can sorta-handle CP77, minus maybe the GPU that you can upgrade later.
EDIT: Forgot, you'll also have to spend some $120 on new DDR4 3200-ish mhz memory, so keep that in mind.
