Shooter is Bad

Thanks for the imput my friends!

I've been tossing the idea of going to Ryzen for a while, as many of my buddies are already there. The thing is... upgrading on my platform will run me over 500 USD, and that's with a RX 580 8GB GPU.

That's with the same RX 580 GPU... On the +side of going Ryzen I can recoup some of the money by reselling my used mobo with the CPU. I'm torn on which way to go... All the feedback any of you can give me would be great. Personally I'm leaning towards sticking with my LGA 1151 mobo. However, it's micro... So, only one PCI-E... Eventually I want to go Crossfire/SLI and it's really tearing me in half thinking about which way to go... All I know is that it's not going to be cheap lol. Also another thing I wouldn't mind a second opinion on, How long could my current rig last? I can manage over 60FPS on most new titles, Obviously not on Ultra on all of them... I have my current rig specs on my profile, I think they show up when you post listings as well... Anywho, Thanks for checking my post out!
