WINDOWS I have a working, clean PC with no issues from TTX Graphics card: 4060 Processor: i5 12400F h650 1TB RAM 16GB Comes with the original boxes for the processor, graphics card, motherboard, and a few other items. It runs 4K at over 300 FPS without lag or any issues, and it has a power-saving mode. I'm asking for 3500, I bought it for more, honestly. And you have a 2-day warranty. If you find any defect, damage, or lag, you can return it and get your money back. Operating System: Windows Processor Type: Intel Core i5 RAM Size: 16 GB
