Building my first PC - Are these specs suitable for the Sims 4?

@MelaTrix18  Sims 4 is much harder on the GPU than the CPU, like most games.  It's more CPU-intensive than Sims 3, and probably more than other comparable games, which may be where you found that information.  What is definitely true is that the lag inevitable in Sims 4 can clear more quickly on a higher-end processor.  There's no way to avoid it entirely, only mitigate its effects.

An RTX 4060 is overkill for Sims 4 even if you plan to play at a high resolution and/or a high refresh rate.  It's more than enough for 2560x1440 at 144 fps, other than the game's unavoiable slowdowns.  If you're planning on playing at 4k, that might be a different story (I'd need to poke around a bit), although 60 fps shouldn't be a problem.  That's not to say don't get the 4060, only that it would be wasted on a lower-res or lower-refresh-rate monitor.  For keeping costs down, you could get a used 3060, 2060 Super, or 2070 and still have an overkill GPU, and maybe upgrade in the future if and when you want to play another game that demands it.

I would strongly suggest upgrading the processor.  A Ryzen 7 5800X is significantly cheaper than a 3700X, according to PCPartpicker, and last generation's best CPU for gaming, the 5800X3D, is barely more expensive.  (PCPartpicker hasn't updated, but Amazon has the price at £224 right now.)  Either one would be a significant upgrade and keep the computer viable for longer, not to mention be able to drive a faster graphics card down the line if you want one.  More CPU power also means better results in streaming, which can be resource-intensive; if you're looking to stream at high quality rather than simply record, the £260 12-core 5900X is the best option.  (The others are more than fine for recording.)  The motherboard you've picked out is compatible with all of these.

The power supply is similarly overkill, and there's no reason to get an 850W unit rather than, say, 650W, unless you're planning to upgrade the GPU down the line.  Again, this isn't a problem, only a detail worth mentioning.  Corsair is the gold standard in PSUs, and quality is much more important than wattage so long as the wattage meets the hardware's minimum requirements.

The storage is fine, the motherboard is fine, and the RAM is fine, although I'd go with a 3600 kit if you can find one.  AMD CPUs love fast RAM, and DDR4 is cheap these days.  Memory is also easy to manufacture at a high quality, so you can simply pick whatever you like from any decent brand and not worry about it.  This is the support list for your motherboard:

Compare the exact product number with what you see on the site, and double-check that the board can in fact run the kit at its maximum listed speed.

If you have more questions, please feel free to ask.  And congratulations on building your first PC, which is an exciting prospect in any context.

Thank you so much for your very detailed and helpful response! So I’m going to change my CPU to the Ryzen 5800X as like you mentioned it’s significantly cheaper and would be better long-term. What’s the difference between the 5800X and 5800X3D? I was comparing prices and the 3D costs around £100 more. I’m willing to spend more if it’s performs better.

Im going to keep the GPU I chose as I do plan on getting a better monitor in the future (The monitor I’m going to buy currently is HP M24FW 23.8). I also plan on upgrading the GPU in the future so I’m going to keep the 850W PSU. All the parts I want are compatible with my motherboard according to PCPartPicker. In terms of RAM, is there a significant difference if I get 3200 compared to 3600?

@MelaTrix18  The X3D is faster in gaming, but only in games that max out the CPU or come close.  So you'd see a significant improvement in games like Cities Skylines or others that are CPU-bound, but not in games that are GPU-bound.  The effects are also more dramatic at 1080p than at higher resolutions because the CPU has a proportionally heavier workload relative to the GPU.  This won't matter at all for Sims 4, ever, but it might for some future game we don't know will exist yet.

This is not a critical choice though.  It's not like the 5800X won't run games well, and you might never see any difference in any game you'll ever play.  Or you might see a difference in theory, but only if you buy a high-end GPU, the kind that sells for over £1,000.  Or you might decide you need the extra performance and buy a used 5800X3D when the time comes.  It's difficult to predict how future games will run but easy to find cheap used hardware.

For what it's worth, the 5800X is better than the X3D for productivity tasks, including video editing.  The reason it's so cheap is that people who need productivity-related performance will go for the 7000-series, or a professional-grade CPU.  The X3D is the best gaming chip available for those who don't deal with professional workloads and aren't ready to upgrade their computers from the AM4 platform, which stops at the 5000-series.  So that's why you're seeing such a significant price difference.

The difference between RAM that runs at 3600 vs 3200 megatransfers per second is small but may be meaningful to you, depending on how sensitive you are to small changes.  I would say that you could see it if you were looking for it but don't absolutely need the upgrade.  But the price difference is so small that it's absolutely worthwhile just in case it's helpful.  I wouldn't tell you to spend £50 more, but for £5, it's an easy decision.  The 3600 MT/s version of the same kit you picked out looks to be only a couple pounds more expensive on Amazon, which makes things simple.

Thank you for your help! I’ll stick with the 5800X for now and change my RAM to run at 3600 megatransfers per second since it’s not that much more expensive. 

I want to use Gshade or Reshade whilst playing my game. Do you think my specs are good enough to play with gshade/reshade? I’ve heard that it can make the game laggy so I want my PC to be able to handle it and still run fast with minimal to no lag.

@MelaTrix18  An RTX 4060 is overkill for Sims 4 even with Reshade present, although I'd suggest trying out Nvidia Freestyle first.  It's not as expansive as Reshade but doesn't need to be installed or updated since it's part of the graphics driver package.  GShade doesn't get along well with Sims 4 these days, so I'd avoid it for now, but using it wouldn't be too demanding from a hardware standpoint.

The Sims 4 graphics engine may not be able to keep up with the demands of Reshade after a certain point, but I don't get the sense that this is a practical problem for most players.  I'm just saying keep in mind that you might have to fiddle with the settings due to how the game works even though your GPU is handling its load without issues.

@joeroot2  The graphics card is the limiting factor for Sims 4 most of the time, with the processor mattering in the occasional situations where the game engine has a lot of data to process.  And really any current gaming-tier hardware is sufficient for Sims 4 alone.  The question is whether you want more power for other purposes: using ReShade or high poly custom content, editing videos, playing other games.  If the answer is no to the last two, and you don't expect to get too ambitious with ReShade or cc, then a recent (last three years or so) i3 or Ryzen 3 and an RTX 3050 would be fine.

If you have particular hardware in mind, feel free to list it for a second opinion.
