Damn dude. You still rocking a 7yr old CPU? I can't believe it works. Rate this...hard to say. It's really old except for the GPU. Did you buy this? or have some other question you are curious about?
Not everyone can simply replace their entire system bar GPU on a whim.
The CPU can still run a lot of games and should not bottleneck the 1050ti at 1080p. The PSU is kinda on the small side considering the power requirements, and upgrading to 1080p monitor will dramatically enhance the gaming experience. That is why I would upgrade the components in that order.
If you own the system why not test it out on the games you wish to play? You can purchase the games on steam and then return them if they do not work well on your PC.
It will able to play those games but do not expect great results. CSGO should work without any problems, but GTA 5 will struggle with your CPU.
I don't own a credit card for the moment.
I'm just playing cs source ( i found it free in the internet, and i am getting 200+ fps) and also cod bo2 ( my friend gave me the installation of it from a CD )
