like Hifi, there are a thousand ways to do this, with a similar number of price points.
Consoles vs PC: equivalent to MUSO vs 500 system.
laptop vs Desktop: equivalent to Superuniti vs separates.
and the cost is pretty much like the hifi analogy. and the questions are the same…how much are you prepared to spend?
And a bit like hifi, everyone will have their own opinion. so I expect that what I suggest will be ripped to shreds… (reminds of a hifi forum I frequent)
assuming that he is not going professional (immediately), then £1500-2000 will get you something along the lines of
PC - desktop 700+ Watt PSU
Intel i7 processor, 16GB RAM (Corsair or Kingston), Asus or Gigabyte mobo with onboard sound, 5.1 surround speakers (ethernet and usb ports are assumed)
two hard disks, 2 TB each Western Digital. if you want to push the boat out the make the C: drive an SSD
Asus or Gigabyte NVidia graphics card ( i tend to match the make of card to the mobo) expect to pay £400 for this alone!
Razer mouse (optional headset and mic - for gaming with friends)
Logitech keyboard
Windows 10 64-bit Professional
24" monitor - IIyama, Dell, Samsung
Which is pretty much what I’m about to build for a family member
And my creds? I’ve been building the family PCs for a quarter of a century - and three of us are serious gamers!
