If you're looking for the best deals on upgrade bundles for your gaming PC, then there's only one place you should be heading to, and that's the nearest Micro Center store to you. Its bundles are almost legendary, and PC enthusiasts will happily drive for hours on end to save hundreds of dollars on the latest hardware.But if you can't get to one, you might think that Micro Center's store on Amazon is the next best thing. However, truth be told, those offers are far from ideal, and many of them lack the really expensive bits right now, i.e. memory kits and SSDs.We're curating all the best Prime Day PC gaming deals hereAll is not lost, though, because Newegg also offers a variety of bundles, and I've chosen four deals well worth considering if you're looking to do a platform upgrade on an older gaming PC.By that, I mean fitting a new CPU, motherboard, DRAM, and SSD. You don't really need the latter for an upgrade, but if the system is using an old SATA drive, then a fresh Windows install on an NVMe SSD will give it a massive performance boost.It's worth noting that for each of the bundles below, Newegg is throwing in a basic air CPU cooler with the Ryzen 5 5500 offers and a 240 mm AIO liquid CPU cooler with the Ryzen AM5 CPU deals, so you don't need to worry about getting a separate chip chiller.$353 AM4 bundle (16 GB / 512 GB )Bundle parts:> AMD Ryzen 5 5500> MSI Pro B550M Pro-VDH WiFi> Team Group T-Force Vulcan 16 GB DDR4-3600 CL18> Team Group T-Force G50 512 GB SSDView DealStarting off with something very affordable (in today's component economy, at least), this bundle is based around AMD's previous generation CPU socket, AM4. Mind you, that's still going, and despite the fact that the Ryzen 5 5500 is 'just' a six-core, 12-thread processor, it's honestly very good for the money.I've built a couple of gaming PCs with this chip and been surprised every time by just how capable it is. To keep the cost of this bundle down, you're only getting a basic MSI motherboard and 16 GB of DDR4, but if it's just a straightforward gaming PC that you're upgrading, then you're not missing out on anything.As for the 512 GB SSD, that will be fine for hosting Windows, a few apps, and one or two games, but since the motherboard has a spare M.2 slot and four SATA ports, you can easily add more storage to the setup.$458 AM4 bundle (32 GB / 512 GB)Bundle parts:> AMD Ryzen 5 5500> Gigabyte B550 Eagle WiFi6> G.Skill Trident Z RGB 32 GB DDR4-3600 CL18> Team Group T-Force G50 512 GB SSDView DealIf the bundle above doesn't have enough memory for your needs, this one should suit you perfectly. Yes, it's $105 more expensive, but that's just how much more 32 GB kits are compared to 16 GB ones, at the very least.The Gigabyte motherboard in this bundle is a little better than the MSI model in the previous bundle, mostly because it supports Wi-Fi 6, whereas the other is just Wi-Fi 5. You might not think that's a big difference, but when you're downloading games wirelessly, the newer system will be a boon.$635 AM5 bundle (16 GB / 1 TB)Bundle parts:> AMD Ryzen 5 9600X> MSI Pro B850-S WiFi6E> Team Group T-Force Delta RGB 16 GB DDR5-6000 CL38> Patriot P410 1 TB SSDView DealPricey but potent, this bundle sports AMD's perky little Ryzen 5 9600X, 16 GB of fast DDR5, and a 1 TB NVMe SSD. Perhaps not the best setup for heavy multithreaded workloads, but it will be absolutely fine for gaming. Yes, even the memory kit is big enough, just as long as you avoid using multiple apps when running a game at the same time.The MSI motherboard is a pretty basic one, as all of its Pro models are generally aimed at the general PC user, rather than specifically targeting gamers. Hence, it only has two M.2 slots for fast SSDs, but it still offers three PCIe slots and eight USB ports on the rear panel.$994 AM5 bundle (32 GB / 1 TB)Bundle parts:> AMD Ryzen 7 7700X> ASUS B850 Max Gaming WiFi W> G.Skill Trident Z5 RGB 32 GB DDR5-6000 CL36> Patriot P410 1 TB SSDView DealThis bundle is clearly the most expensive of the four, coming in at a little under $1000. Naturally, the 32 GB DDR5 memory kit and 1 TB NVMe SSD are mostly to blame for that, but you are still getting a decent 8-core, 16-thread processor in the form of the Ryzen 7 7700X and a very nice Asus B850 Max Gaming motherboard.With four PCIe slots, three M.2 slots, and eight USB ports on the rear IO panel, it's reasonably well equipped, but I chose this particular bundle because of the motherboard's aesthetics and G.Skill's really solid Trident Z5 memory kit.Put all these parts together in a gaming PC, and you'll have a setup that will serve you well for many years to come. It should outlast the RAMpocalypse, at the very least.
