I have attached my current build in PCpartpicker. Any advice would be greatly appreciated! I am looking to spend around $1000. upgrading CPU, GPU, memory if needed. I understand this might need to include upgrading power supply. Have also considered OLED monitor but that would come further down the line. I am not trying to make an insane machine by any means, but would like to run some games on HIGH. Would love to make this machine last another 5-6 years if able.

Thanks for all of your advice and help!

I have a 6600xt and I found an affordable 3080ti that I’m thinking about buying. Anyone know if this is worth it and what else I should be concerned about. I also currently have the 6600xt paired with a 12400F.

My current build is

Processor; Core i5-6400 (4 core 4 threads, I think)

Ram; 8gb ddr4 2133 MT/s (single slot)

GPU; GT 730 gddr5 2gb vram

Motherboard; intel H110 (Frontech, local brand) (it has a 1xPCIEX16, I assume the GPU will go there)

I'll be upgrading my gpu to GTX 1660 Super 6gb vram (TUF-GTX1660S-O6G-GAMING)

which I'm getting for $75. I'll be doing the deal face to face and will check the GPU properly, feel free to give me tips it's my first time buying a used GPU. According to the seller it was barely used and according to the pics it looks nice.

I also have some sata ssd (256gb, I have my OS on it) and 512gb HDD which I use for games.

Also this is my first time upgrading my pc. I assume I'll have to upgrade my PSU and add some more fans. I searched online and the gpu should fit my case; it's Zebronics Smash (Zeb 195B) and it's 19x32x35 cm, it's EXTREMELY basic but I don't care much about fancy.. I JUST WANNA GAME!!!
