Quick Answer

For strategy and sim games at R25,000 in Gauteng, prioritise CPU single-thread and RAM: a Ryzen 7 7700 (or 7600) with an RTX 4060 Ti, 32GB DDR5 and a 1TB NVMe. That keeps Civilization VII turn times short, Cities: Skylines II at 60 fps mid-map, and large Total War battles fluid at 1440p.

Strategy and sim games are CPU and RAM games

Late-game turns in Civ, dense Cities: Skylines II saves and 10,000-unit Total War battles stress the CPU and memory far more than the GPU. So spend on the Ryzen 7 7700 (8 cores, R6,500) and 32GB DDR5-6000 (R2,200), then pair an RTX 4060 Ti (~R8,000). A 1TB NVMe slashes the long load and autosave times that plague big simulation saves.

Why 32GB and fast storage matter most here

A sprawling Cities: Skylines II city or a modded Stellaris galaxy can push past 16GB RAM, where stutter and swapping begin. 32GB removes that wall. Turn times in Civilization VII and end-game Stellaris ticks shrink with stronger single-thread performance, which is exactly where the Ryzen 7 7700 helps. The GPU mainly drives resolution, so 1440p High is the comfortable target.

SA buyer and upgrade notes

AM5 leaves a clean upgrade lane to a future Ryzen chip, the part most worth upgrading for strategy fans chasing shorter turns. Buy locally for in-country warranty. A 1440p panel at 100Hz+ is ideal: strategy does not need 165Hz, but the resolution gives you more visible map and UI at once.

FAQ

What matters most for strategy and sim PCs?

CPU single-thread performance and RAM. Turn times, simulation ticks and large battles are CPU and memory bound, so a Ryzen 7 7700 with 32GB DDR5 matters more than a top-tier GPU at this budget.

Is 32GB RAM needed for city builders?

For large Cities: Skylines II saves, heavily modded Stellaris or detailed Anno cities, yes. 16GB causes stutter as the simulation grows; 32GB keeps big saves stable.

Will this build shorten Civ turn times?

Yes. The Ryzen 7 7700's strong single-thread speed and 32GB RAM keep late-game Civilization VII turns short, where weaker chips slow to a crawl on huge maps.

TIP

Pro Tip

strategy and sim builds, put your save folder on the NVMe and keep at least 8GB RAM free. On this rig that keeps late-game Civ turns and big Cities: Skylines II saves snappy.
