I was actually looking at buying a Dell Alienware Aurora R12. I’m working in Russia so not easy to build my own and buying components here is even more expensive than elsewhere in the world.
The specs I was looking at are:-
Intel Core i9 11900F, 2.5 GHz - 5.2 GHz, 32768 Mb, 1000 Gb SSD, DVD нет, nVidia GeForce RTX 3080 Ti 12288 Mb, 1000W, Windows 10 Home, черный, R12-7899
Works out to be around $4k which is more expensive than in the UK but I don’t have much choice unfortunately.
