Trade Negotiation Scenarios

Three standard paths depending on accessory verification during the meetup.

Scenario A (Recommended)

Clean Desktop with Original Coolers

Computer A + $150 – $300 Cash

Computer B includes the original XFX triple-fan heatsink and retail boxes. The loop is pristine. Computer A adds cash to balance the 9800X3D, 24GB VRAM, and 64GB DDR5 hardware advantage.

Scenario B (Risk Discount)

Missing Stock Cooler / Maintenance Due

Straight 1-to-1 Trade ($0 Cash)

If the desktop seller cannot provide the original factory air cooler for the RX 7900 XTX, the GPU loses warranty coverage and retail liquidity. The trade is fair at an even $0 cash swap.
