CPU problem

[XaloCaH]

Hi everybody, I have a problem. My apu is an amd a10-7870k whit 4 cores and 4 logical. As you can see in the picture, task manager says that its a duo core whit 4 logical...

How can i enable the other 2 cores for a normal game experience ? Is is from the bios ?
Is it time to change my cpu ? And what can you prefere me ? Its an FM2+ socket and i dont have the finance for a new mobo

 

Benchmarks:
GTA V - The fps is boucing around 20 (in the city) to 40-50 on the highway. (Normal settings/ around 1200mb/2000 vram usage)
GTA IV -The fps is around 10-15 (in city) to 30-40. I dont think that its normal. (very high/Almost maxed out settings)
CS:GO-no problem, max presets 100fps+
League of legends: medium settings- 70fps (+/- 10)

All are on 1920x1080 resolution 

Full specs:
CPU-AMD A10-7870k APU
GPU-RX 460 2GB
Mobo- Asus A88X-PRO
RAM- 2x4gb Adata 1666mhz
PSU- 600W N-joy whit 80+ certificat
HDD-1TB WD Black

3 120mm fans for cooling

thats because the architecture its based on, Buldozer, has its cores in pairs, shareing some stuff which is also the reason why the FX line of CPUs are shit

The other 2 cores are already enabled, its because these older AMD cpu's used 2 cores in one "block" so to speak, windows just reads the number of blocks.

 

Don't bother upgrading on a dead platform, wait until you can afford new cpu/mobo/ram and go for a ryzen build.

Also note that GTA 4 is horribly optimized.

 

It takes a lot to run that game, even more so than its successor.
