Looking to upgrade my desktop for better mod support

@Lovelyshawn  The issue here may be the processor and RAM, or it may be your hard drive, particularly if you've installed Sims 4 on an HDD.  Your graphics card is still fast enough to handle ultra graphics settings, and the GPU isn't as involved in loading times as the other components.  (That's not to say it makes no difference, only that the 1060 is unlikely to be the limiting factor at any point in the loading process.)

Your processor could only be upgraded to another 2nd- or 3rd-gen Intel Core processor, with the i7-3770K being the most powerful option in that category.  This is a limitation of the motherboard.  A newer CPU would mean a newer board and new RAM, and at that point, you might as well build a new computer.  If you want to go that route, even if you're reusing a couple of components, let me know.

You might be able to find a used i7-3770K for a relatively cheap price.  It looks like it's going for around $60 on Ebay, and Craigslist or Facebook Marketplace might have a cheaper offer, albeit with more risk.  But I'm not sure it's worth investing even that given the relatively small performance improvement.  Perhaps more relevantly, this computer is old enough that the other components might not hold up for much longer, so this may be a good time to look into a new build.  Still, it's your choice.  A faster CPU and some new thermal paste could make enough of a difference to be worth the investment, and your hardware might last a few more years, depending on the luck of the draw.

I don't know what speed your RAM is, but your processor and motherboard will only support DDR3, which can't go above a certain speed that is relatively slow by modern standards.  Still, if your current modules are running at a slow speed even for DDR3, upgrading to the fastest kit available might be worth the price.  You should be able to see the speed in the Task Manager.

If you do have Sims 4 installed on an HDD, then installing an SSD would make a significant difference.  I doubt your motherboard has an M.2 slot, but a SATA SSD uses the same type of port as an HDD, and it would be more than fast enough to remove this as a potential bottleneck.  Plus, the drive could be reused in a future build, so it wouldn't be a waste of money no matter when you replaced this computer.  I don't know where you live, but this is a good option in the U.S. in either 500 GB or 1 TB form:

If you have more questions, please feel free to keep asking.

Since checking my desktop, I'll have to take apart the whole thing which at the point I'd be better off with a new desktop anyway but again thank you for your response!

@Lovelyshawn  You shouldn't need to take apart the desktop to add another drive.  The SATA ports on the motherboard should be exposed, so all you'd need to do is find or buy a connector and find the power cable that connects to your existing drive.  But if that's not feasiible, then I guess a new computer is the better option.

@puzzlezaddict Sorry one more thing, it wouldn't be feasible in my case so I'm looking to just overall get a new desktop build specifically for The Sims 4, and use this for parts. Would this be a good fit to run my game with all my cc and more with of course the least amount of loading times paired with my GTX 1060? (I know it'll still take some time to load though) If yes, I'll go ahead and cop. Might increase the RAM on it in the nearby future. Thank you again!

@Lovelyshawn  I don't think this would be a good option on its own.  I can't tell from the product description, but it's very likely that the power supply in this computer is insufficient for your 1060, and the case might not even have enough space for the GPU.  So while the processor is better than what you have, you'd actually be giving up performance.

In theory, you could harvest the motherboard, CPU, and RAM from this computer and pair it with your existing GPU and power supply, but in practice, these types of computers usually have proprietary PSUs and motherboards that aren't compatible with standard components.  So unless you already had a Dell desktop and Dell didn't change its configuration from your PC's generation to this one, the parts wouldn't be compatible.

What exact computer do you have right now?  Are you comfortable building half a new PC?  There are other options here, for example buying a used processor and motherboard on Craigslist or Facebook Marketplace.  A CPU and board from, say, four years ago might be very cheap right now considering how much faster current processors are.  You could swap out those and add some newer RAM (DDR4 RAM is mostly cheap these days too) while keeping the other components.  It won't be as cheap as this desktop you're looking at now, but it'll last longer and be a much more significant upgrade.

Ah okay thank you and sorry for late response, just finished my shift at work. Currently I have an HP Z210 workstation build. I'm interested in building half the pc like you've stated because I'm just ready to take my Sims gameplay to another level lol. I'll definitely take a look around and let you know what kind of motherboard and cpu I have an eye if that's okay but what kind of screwdrivers would you recommend to take out my current motherboard?

@Lovelyshawn  Before spending any money, take a look at the power supply and its connectors.  It's possible the PSU is a proprietary design too, not compatible with standard motherboards.  The CPU cooler may or may not be usable, and even if it were theoretically compatible with a newer processor and board, it might not provide sufficient cooling for a newer model.  (That depends in part on what new CPU you bought.)  The graphics card should be fine, but double-check that too: does it use a supplementary power connector, and if so, how many pins does that connector have?  The hard drive is definitely going to be usable in any system.

The idea here is to figure out which components are cross-compatible and therefore how much you'd need to spend on a new build.  If nothing but the 1060 and the HDD are salvageable, do you want to build or buy an entirely new, or new to you, system?  Or do you want to just get the fastest CPU your current setup would support and hope for the best?  Even with a smaller budget, you'd have a lot of options if you were willing to buy from Ebay or the like, but that's your call.
