Help Upgrading or rebuilding APU

[Izec]

Budget (including currency): $330

Country: US

Games, programs or workloads that it will be used for: General browsing/computing, Discord, Minecraft, Dota 2, (would be nice - Raft, Wreckfest) 

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): 

This PC does still currently run but cannot run any games besides minecraft on lowest settings. 

I'm wondering if I should use parts I have (listed below) or find an old workstation and upgrade that (like LTT video: https://youtu.be/YLC9rZ2e0Ms )

 

Current PC Parts:

CPU: AMD A6-5400K - A6 Series Trinity Dual-Core 3.6 GHz Socket FM2 65W AMD Radeon HD 7540D Desktop APU

MB: BIOSTAR Hi-Fi A85S3 FM2 AMD A85X (Hudson D4) SATA 6Gb/s USB 3.0 HDMI Micro ATX

Case: Rosewill R218-P-BK-450W MicroATX Mid Tower Computer Case

PSU: 450W Power Supply ^^^^ (was included with the case)

RAM: CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin PC RAM DDR3 1600 (PC3 12800)

HD: I already have a 128GB TOSHIBA and 500GB Seagate Desktop HDD ST500DM002

Extras: XIGMATEK FCB (Fluid Circulative Bearing) Cooling System Crystal Series CLF-F1454 140mm White LED Case Fan (front fan)

 

I've considered looking for upgraded chip within same socket but it seems limited. And I'm not sure if getting a GPU would really increase speeds. I also recently found the site jawa.gg and was considering one of the low cost options there.

 

Any guidance or help is greatly appreciated!

You can invest your whole budget into a GPU, then save up to upgrade everything else. Your PC is so old that literally no one thing that can be upgraded without upgrading everything else.

With 330, you may be able to pick up a used low end gaming PC on a place like eBay or FB marketplace. If this was an AM3 socket I could see a few creature comfort upgrades, but FM2 is such an old socket that it's time to start fresh. 

 

Rx 470 $100

B450 $50

1600 50 (see if you can get the stock cooler with it if possible, if not: +$15)

Case: can be reused

PSU: would probably replace ($60)

Ram: 16gb ddr4 ($45-50 used or new)

Total: $325-350.
