I got my hardware and thought I'd close this out.
I bought:
- MSI MAG Z790 Tomahawk (Amazon) - $219.99
- Intel Core i5-12600KF (Amazon) - $152
- Seasonic Focus GX-850 (Amazon) - $102
- Palit 4070 Super (Wootware) - R13799
- G.Skill F5-5600J3636C16GX2-FX5 Flare X5 32GB (2x16GB) (Wootware) - R2399
I used a 1TiB SN750 NVME SSD I had.
My Amazon order cost ~R6k (motherboard and CPU, PSU was bought in a different order).
Item for item, the same CU and motherboard, from Wootware, would have cost R18k.
I got lucky, in that Amazon had the CPU at $150 after I created the original post.
The motherboard had a coupon for $10 off too.
Every item would have cost less from Amazon, but the GPU would only have been about R1k less and the RAM about R200 less. (including shipping and tax and everything, total cost it would have been cheaper).
Because RAM and GPU are the items I've personally had that failed the most, I opted to buy it locally.
I sort of regret getting that CPU in a way, I realised after AMD is much better for gaming, some of the lower core count AMD CPUs specifically.
To everyone's point, just installing Baldur's Gate 3 took > 128GiB of space, there is no way you can game on anything less than 512GiB in my opinion.
Last but not least, the RAM is EXPO (AMD), but the motherboard supports it just fine and runs at the much higher speed as advertised by the RAM.
The screen I have is 1440p and every game I've installed so far is pretty much limited by the screen I have, 1440p @ 60Hz and the FPS is just solidly locked even at the most ridiculous settings. (Don't own Cyberpunk so haven't tested that one)
