Help with buying a new gaming pc to play all The Sims 4 and Packs

@Simsfan8989  Yes, an Alienware Aurora R9 would run all Sims 4 content, plus any custom content you could find, on ultra settings.  Looking at the various configurations though, the computer is overkill, possibly massive overkill, for Sims 4.  Do you have other games you want to play on this system, now or in the future?  If not, then the extra power is probably a waste of money.

If you'd like to see other options, just list your budget and country, as well as other considerations that matter to you.  Please also let me know what resolution your monitor has, or what resolution you'd like if you're planning to buy a new monitor.  If you don't know, that's fine; it's just that higher resolutions require a bit more graphics card power than lower ones.
