Hello,

Bellow is my parts list on parts picker. I would like to get some ideas for what would be some good upgrades to do will I what for graphics cards to fall in price.

 

parts other then the CPU cooler, case and all fans are older and I got them from a friend. 

 

I was thinking a $20 wifi card and maybe a new and higher capacity power supply for better hardware in the future. Also maybe adding a larger HDD or SDD. Motherboard has 6 sata ports.

Just keep the system as is. No point putting more money into a dated system like that
