The TBG DIY PC Build Guides

Introduction to the TBG PC Build Guides

Welcome to TBG’s DIY PC Build Guides! This is where you’ll find all the best PC builds on the ‘net, from ultra-compact home office PCs to screaming-fast gaming towers. In total, we offer 15 distinct DIY PC Build guides, constantly updated with the latest and greatest components.

The December 2025 Updates

This holidays are always an exciting time to build a new PC, although current market conditions have made that a bit trickier, as we’ll explain in a moment. The good news is that a lot of gear is available at great prices, including our top GPU picks, the Radeon RX 9060 XT 8GB and 16GB at under $300 and $400, respectively, the GeForce RTX 5070 12GB at under $550, and the RX 9070 XT 16GB around $650. This is huge change from spring and summer 2025, and actually pretty good for any GPU in its year of release – historically it’s been hard to grab GPUs at all for a year after release. Given that AI is gobbling up lots of GPUs, just getting your hands on a GPU is great, and getting it at or below MSRP is phenomenal.

But PC builders are in for a bit of pain when it comes to RAM – we are now officially in the RAMpocalypse! We’ve been reporting on this since September, and at this point, RAM is approximately 3-4x more expensive than it was in the summer of 2025. The one bright side, which we honestly didn’t expect, is that you can actully still buy any RAM at all. What we’ve done in our builds is downgrade the RAM spec (either a lower capacity or less aggressive “timings”), in order to give you what you need now without paying through the nose. Another great options is to buy one of pre-built systems we list in some of our guides or in our Desktop PC Buyer’s Guide, as these systems aren’t flying off shelves quite as quickly as RAM kits.

So with that said, with the holidays coming, we’ll likely see great deals on just about every PC component… except for RAM!
