My temps when my CPU is idle is at 50°C. Stock cooler with Artic MX4 paste. Should I just get a cooler for my current CPU and upgrade my system specs later or buy a new cpu, motherboard and ram? Is the current CPU good enough for upcoming games like Cyberpunk 2077, Anthem and Biomutant?

Current specs are:
AMD Phenom II x4 965 BE
24Gb of DDR3
MSI 990fxa-GAMING
RX 470
NZXT Source 530
Samsung EVO 850 256 Gb SSD
Seagate Barracuda 2Tb harddrive

I would keep current case, storage, GPU, and optical drive.
