Quick Answer
For a Wits Computer Science student in Hatfield, build around Ryzen 7 7840HS, Ryzen 7 7700 or Core i7-14700 class chip with 32GB and a 1TB Gen4 NVMe SSD - that is the right call. R25,000 is the sweet spot for a do-everything rig: a Ryzen 7 or Core i7, 32GB RAM, a 1TB SSD, and an RTX 4060 Ti / RTX 4070-class GPU.
What R25,000 buys you
Put the money where Computer Science needs it: RAM and a fast NVMe SSD matter far more than the GPU - most CS courses never touch 3D graphics. A sensible spec is a Ryzen 7 7840HS, Ryzen 7 7700 or Core i7-14700 class chip, 32GB, a 1TB Gen4 NVMe SSD and an RTX 4060 Ti 8GB or RTX 4070 12GB. Plan for roughly R24,000-R25,000 for a Ryzen 7 / RTX 4070-class build currently stocked at Evetech. The common mistake is a flashy GPU paired with only 8GB RAM - you feel that shortage in compiling large Java projects, running multiple containers, and keeping 30+ browser tabs plus a VM open at once long before any graphics limit.
Built for Computer Science work
Your toolset is IntelliJ IDEA, VS Code, Eclipse, Python, Java JDKs, Git, and Linux VMs or Docker containers. The real load is compiling large Java projects, running multiple containers, and keeping 30+ browser tabs plus a VM open at once, which is why Docker, a Linux VM and an IDE together can eat 12-14GB before you open Chrome and a fast SSD pays off daily - datasets and VM images add up fast. A discrete GPU is optional for pure CS; integrated Radeon or Iris graphics handle the IDE fine.
Laptop or desktop from Hatfield?
Commuting from Pretoria to Braamfontein, a laptop you can use on the Gautrain or between lectures beats a desktop stuck at home. Rent res near campus and a desktop gives more per rand - but only if you will be there. Either way, buy locally so warranty claims stay in South Africa rather than couriering a dead machine overseas during exams.
After-hours gaming and side projects
An RTX 4060 Ti 8GB or RTX 4070 12GB is not just for study: an RTX 4070 runs 1440p Ultra at 80-110 fps and dips into smooth 4K on lighter titles. That headroom also speeds up local model training, editing and rendering side-work.
FAQ
Does NSFAS cover this?
No. The NSFAS laptop allowance is R5,200, which does not reach Evetech's R8,000 entry laptop, let alone a R25,000 build. Treat it as a deposit and budget the rest.
Is the warranty worth it?
Yes - a machine carried to campus daily takes knocks. Stick to gear with a local Evetech-backed warranty so a repair never means shipping abroad mid-exam.
Should I prioritise the GPU or the SSD?
For Computer Science, a discrete GPU is optional for pure CS; integrated Radeon or Iris graphics handle the IDE fine. Spend the saved money on a 1TB Gen4 NVMe SSD - fast storage cuts load and boot times you feel daily.
