[max13]

[SOLVED] - Please help me decide what should i upgrade first.

I already have a PC . Its an old one. And I don't want to spend more than 500$ at this moment. So I'm thinking of getting a new CPU or GPU first. My current pc spec CPU - I7 3770 MB - Asus P8Z77 1155 GPU - Power Color RX 470 4gb Ram - Kingston DDR3 4*4 PSU - Thermaltake 650w Smart...

Due to this forum, I decided to upgrade a GPU but i only have 500$ to spend

And I'm thinking of Galax RTX 2070 mini
, Rx 5700 and Rtx 2060s or else. But I can't decide so i need your help. What GPU i should get, and would it be good with my current PC spec?

I'm so sorry if you get confused by my English.

I wouldn't upgrade the GPU until you've changed the PSU out to a more reliable unit, preferably one made by Seasonic. How old is that Thermaltake PSU again? Where are you located and what is your preferred site for purchase?

I replaced my PSU two years ago.
Should i change my PSU too?

I live in Thailand. So Amazon would be nice but i really don't want to spend extra money for shipping product thoo. Do you have any recommendations for the purchase that available for my country?

Thank you so muchh
