Benchmarking is crucial, as it’s the best means to tell if you’re getting what can be expected out of your components.

PC Building Simulator exists in the virtual space. So real world restrictions no longer apply.

With that, some add-ons allow us to jump forward in time and see what PC tech might look like a few years down the line.

And this mod adds in G.SKILL’s popular line of RAM modules, the Ripjaws, except you’ll now have access to 32GB, 64GB, and 128GB variants.

There’s no telling when you’ll actually need that much RAM in your system. But with these options, you’ll be able to future proof the hell out of your builds.


6. PCBS RAM Creator

More RAM = faster system.

This seems like a PC building myth that still seems to be a common misconception to this day.

Though such a simple fix won’t always work, seeing as PC systems are much more complicated than that… but that doesn’t stop people from overloading their systems with RAM they won’t even end up using.

If the 128GB Ripjaws still weren’t enough to feed your memory hunger, the PCBS RAM Creator allows you to create completely customized RAM modules for whatever sizes and speeds you may think you need.

With this next mod, you’ll easily be able to get your hands on an RTX 3080 for your virtual builds. Which should tide you over until the real thing becomes available.

While the tech industry is all about staying up to date and moving forward, there’s a whole different world dedicated to retro PC builds.

Going back in time and seeing how far you can push some older components is only part of the fun. And hunting down the actual parts can be quite challenging in itself.

This next mod gives you access to some of the older AM3 components to play around with, making it much easier to get a retro build going.




Check Out This Mod

If the 3080’s 10GB of VRAM just doesn’t cut it, this Aorus GPU should be more than enough.

HairlessMonkey’s Gigabyte Aorus card comes with a whopping 16GB of VRAM running at 4800Mhz, blowing the default 8GB 3200Mhz vanilla version completely out of the water.

The 16GB will be available at level 14 at the same time as the 8GB version, giving you a much more powerful option for those higher-end builds.

Of course, the card comes with RGB capability as well, for that added gamer aesthetic.
