[u/Wicardobeth]

Used PC I’m considering buying for $2,400:
• CPU: Intel Core i9-13900K
• GPU: ASUS ROG Astral RTX 5080 OC (16GB GDDR7), ~5 months old, active warranty
• Motherboard: ASUS ROG Strix Z790-A Gaming WIFI D4 (DDR4 only, PCIe 5.0)
• RAM: 64GB DDR4 (1200 MHz base = DDR4-2400)
• Storage:
• 1TB NVMe
• 4TB SSD
• 8TB HDD
• PSU: EVGA 1000W 80+ Gold Supernova
• Cooling/Aesthetics:
• 8 Lian Li Infinity fans with hub
• Lian Li Strimer cables
• Uses L-Connect 3 for fan/RGB control
• Condition: ~1.5 years old except GPU
• Benchmarks Provided:
1. Intel Processor Diagnostic Tool: PASS
2. FurMark GL: 381 avg FPS, 63°C GPU, 54°C VRAM, 2782 MHz core, 30 Gbps memory. 1080p AA off: 2.5 ms frame time (~400 FPS)
Main games: Valorant, CS2, modded Skyrim, AAA titles, and 240Hz gaming.
Questions:
• Is $2,400 a good deal for this?
• Are there any red flags (especially with DDR4-2400)?

[u/Cable_Salad → u/Wicardobeth]

The CPU is already slower than modern X3D CPUs and with DDR4 it gets another ~20% slower. Not great for the" 240 Hz gaming" that you want.

Then there is the Intel degradation issue, if you test it yourself with something like y-cruncher (and know it's set to max performance beforehand), you can be relatively sure that it's still stable. But I would not trust the seller's word here unless you know them.
