Evidence-backed reasons
Why Rigwise selected it
- 01MSI GeForce RTX 4090 Suprim X 24G at 4K (3840 × 2160) returns Aurora Protocol 95 fps, Circuit Legends 240 fps, Ridgeline Rally 157 fps, Kingdoms of Ash 140 fps average against your 120 Hz target (some figures are modelled estimates, marked in the performance table).
- 02The build totals $3588.9 of your $4000 budget, leaving $411.1 unspent (89.7% used).
- 03Nothing in this build is starved: 64 GB of memory and a 2000 GB drive for 4K (3840 × 2160).
- 04Corsair SF1000 (2024) leaves 28.5% headroom over the 778.3 W estimated load, at or above the 12% this profile requires.
- 05All 13 compatibility rules ran against these parts with no errors and 11 explicit passes.
Visible constraints
Trade-offs to accept
- 01You are paying a premium for the top of this budget: $3588.9 buys the frame rate, not the best price-per-frame in the catalog.
- 02Corsair SF1000 (2024) is an SFX unit in an ATX bay. An SFX-to-ATX mounting bracket is required.
- 03The 6000 MT/s kit will run at up to 5600 MT/s on this platform.
- 04Frame rates for Aurora Protocol, Circuit Legends, Ridgeline Rally, Kingdoms of Ash are modelled estimates rather than direct measurements of this exact card.
