After several years as a graphic designer, I wish to come back to my youth love by practicing again 3D modeling and rendering under Cycles in the field of architecture.
But I don’t know where to go for a PC configuration around 1500€.
Nvidia 2070 super, Ryzen 3700X, 32 GB of DDR4 for full system. Though with that kind of money, I would really look around if I could squeeze in Nvidia 2080 Ti. The price is already 2/3 of your budget tho.
It depends. In this price range (~1500€), you can find a prebuilt system with roughly the same specs with a premium of around 10-20%, depending on who’s building it. A branded system, i.e. from HP or Dell, will always be more expensive compared to an system assembled in a local store or a smaller local brand, but these large companies offer a superb after-sales support, have local dealers in many countries, so, they charge more for that.
