Quick Answer

The RTX 5070 Ti (around R18,000 to R21,000 in SA) renders modded Factorio at 4K with ease, but the game is CPU-bound, so the card is about smooth high-refresh visuals rather than megabase speed. Its 16GB of VRAM handles every HD texture and overhaul mod without strain.

Factorio Is A CPU Game, Not A GPU Game

Factorio simulates belts, inserters, trains, and circuits, and that simulation runs on the CPU. The RTX 5070 Ti draws the clean 2D factory at 4K effortlessly and never becomes the limit. Late-game performance is measured in UPS, and UPS drops when the processor can no longer keep up with thousands of entities. No GPU upgrade fixes that, so the 5070 Ti's job is to keep rendering buttery on a high-Hz 4K panel while leaving you a capable card for other games.

There is no official Factorio remaster; the 4K look comes from HD texture, lighting, and terrain mods. These add polish without GPU cost.

Recommended Visual Mods

Alien Biomes adds varied terrain, high-resolution overhaul mods sharpen machines, and lighting tweaks improve night scenes. Bob's and Angel's add scope and visual variety for bigger builds. All of these are GPU-light, so the 5070 Ti runs them at 4K above 120fps in normal factories.

Build Priorities In South Africa

Spend on the CPU first: a high single-thread processor, 32GB-plus of DDR5 for big saves, and a Gen4 NVMe SSD for quick autosaves. The 5070 Ti pairs well with a 4K 120Hz or 144Hz monitor and a 650W-plus quality PSU. Keep airflow healthy in warmer rooms.
