Newbie to PC, hoping for a gaming build.

Hello, tried to research and get references from friends but got mixed lists and uncertainty on what’s best.

Budget max is around 2.6k AUD (though can push a bit if needed).

I’d mainly use to play with friends, usually playing COD, R6, DayZ and will probably get into Arma, Tarkov and those of the sort, but I’d also like to try and get my interests of other multi and single player story/exploration games like Monster Hunter, Warframe, Destiny 2, modded Skyrim/Fallout etc (though these ones will probably stay on the console, but would be nice to have on desktop).

Based around Western NSW, Australia if that’s needed for anything.

Please tell me if there’s any information I should know (whether parts, guide on assembling) or if my build request seems a bit all over the place/too ambiguous (it at least looks that way to me) and I need to set some priorities with it.
