Improve the PC you already own
Keep what still does the job. Compare a specific change with doing nothing, and verify the parts that connect it.
1. Record your existing PC
Select exact models or paste a plain-text list. Your browser cannot silently identify installed hardware. Pasted matches always require your confirmation; no pasted URL is fetched. This inventory uses one model per category; the expert builder supports multiple cards, kits and drives.
2. Compare a specific change
Each phase is a complete interim configuration and is checked again. Unknowns still need exact support evidence. Comparable game or application tests are required before claiming a performance gain.
3. Compare the full platform cost
Include the motherboard, memory, cooler or mounting kit, PSU/cables, operating system and accessories affected by a swap. An empty quote is unknown, not free. Owned parts stay separate from new spending.
