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 November 2025 Updates

Heading into the most exciting time of the year for PC builders (i.e., the holiday!), we have some really good news and some really bad news. The good news is that video cards are all available at or near their MSRP, and sometimes even a bit under MSRP. In terms of GPUs, both Nvidia and AMD have good deals available, at different price points. Among our favorites are the Radeon RX 9060 XT 8GB and 16GB at under $300 and $400, respectively, the GeForce RTX 5070 12GB at under $550, the RTX 5070 Ti around $750, and the RTX 5080 16GB at $1000. 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.

And now for the bad news – the RAM market is in crisis mode, and it looks like it will be getting much, much worse. We’ve been updating this page every few weeks since September with news on this issue. Now it seems we have to update it daily. In short, we literally saw RAM prices go up by 50% in one week, and that was after prices had already gone up 100% in a month. We predict that by Black Friday, Nov. 28th, it will be impossible to buy RAM on the retail market. Yes, it’s that serious. And OEMs are not immune – the news has it that big companies like Dell and HP are soon going to have a whole lot of trouble selling PCs because they won’t have RAM to ship in these PCs. So our advice is (a) buy RAM today, like seriously as soon as you see this, because the RAM will be gone tomorrow, or (b) buy one of the remaining 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. We’ll update this page once we’ve made the call that the RAM market is dead and it’s time to skip even considering building a PC!

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