Upgrade my old PC: need an advice!

Hi everyone!

My specs is:
ASRock M3A770DE
AMD Phenom X4 925
8 RAM
450 Power

I want to upgrade my GPU to play some games like CS GO, rust and rainbow six siege.
I 100% understand that my specs is a trash and I should just buy totally new PC, but I need some good GPU (not a new one, of course) to play these games.

What should I buy?
I'm thinking about 1050 or 1050ti. But this motherboard only pci 2.0, if I understand right.
What would be the best and not a stupid (but rational) choice?

 

What size of monitor are you running? I got a MSI GTX1060 6G and it runs fine on a 27 monitor that is 2560x1440. Witcher III might give it a run for it's money but I think my setting would work since I am not going 4K. Also update your BIOS to the latest as well for this old of a board. I think a 1060 would do better for your need otherwise get a 1070 if you can find on the cheap. Because if you replace it your GPU will still be up to snuff to game when bringing it over to the replacement system.

On this list if possible upgrade the CPU is it isn't too much as well.

I would try to get the max ram at the fastest speed as well.

All while making sure this fits your budget and doesn't go overboard.

Here's the info to your board.

A second-hand GTX 1060 6 GB would be a decent option that you could migrate to a new system once you have the funds to upgrade the rest of your components. Don't waste money on a new CPU and/or RAM for your present machine.

 

Current best deal for 1080p gaming is a RX 570, used or new.

 

Used RX580 would be also a good idea.

And overclock your CPU.
