Specifications:
Processor: Intel Xeon E5-2650-v2 server processor, 3.0GHz turbo speed, with an air cooler sufficient for acceptable gaming performance. Its performance is close to a 10th gen i3.
Graphics Card: RTX 2060 6GB from Gigabyte, supports ray tracing and DLSS.
RAM: 16GB (2x8) DDR3, speed 1666. The reason it's DDR3 is because the processor is old, and you can upgrade the RAM.
Motherboard: X79, only supports Intel Xeon processors, does not support Intel Core.
Storage: 1TB HDD.
Power Supply: 550W.
Honestly, the PC is good, not amazing, but it's suitable for gaming at 1080p. In most games, it will give you over 80-100 frames. If you want to upgrade the processor, for example, you will have to upgrade the motherboard, RAM, and get a cooler.
You might notice a slight slowness during startup due to the HDD. You can install an SSD for the system for about 200 SAR, and you'll be good.
I play heavy games on this PC with slightly reduced settings, and it gives very good performance.
Note (Does not come with a mouse, keyboard, or anything, just the PC alone with the power cable only).
Price: 1200 SAR, reasonably negotiable.
