We built a Prime Day PC for less than $800, and we didn't even have to use an 8GB GPU

The first component here is vital because, as you can see, it comes with a free 1TB SSD that will save us $57 on our build. The dynamite Ryzen 7 5800XT comes with 4.8GHz peak clock speeds and eight cores of Zen 3 power. The drive in question is a Team Group MP44L M2 NVME, which earned four stars in our review, where we called it "a budget drive done right." This CPU also comes with AMD's capable Wraith Prism cooler, saving us vital cents on our build. If you insist on a third-party cooler to keep things quieter, grab this $20 Thermalright Assassin Spirit that won't send us over the $800 mark.

All-time low price!

This nifty AM4 board will seat our AM4 chip and the DDR4 RAM we'll be recommending in the build. It comes with Wi-Fi 6, more than enough slots and ports for our needs here, and a nice VRM heatsink. Overall, it looks cool as heck.

AMD wins again in our budget build as it did in the $1,600 build. Get $30+ off this card with 3290 MHz clock speeds and crucially, 16GB of VRAM. If you want a 16GB card from Nvidia, you won't find one for less than $400, more than half our entire budget.

We're back to Newegg for our RAM. A build of this budget demands DDR4, so we've picked the excellent Patriot Viper Steel. We wanted 32GB for a build that lasts, even if 16GB would have saved slightly more. This DDR4-3200 kit will suit our build to a tee, but keep an eye out for cheap DDR4-3600 kits, too.

Say what you want about white cases, this NZXT H5 flow is a stunning 37% off and looks absolutely brilliant. It can support plenty of fans should you want to upgrade to liquid cooling down the line, and has a tempered glass side panel. It's also built using premium materials, not papier-mache like most PC cases in this price range.

This MSI MAG A650BN will deliver all the juice we need to power our 9060 and 5800 XT, but doesn't break the bank. It's not modular, but you'll really struggle to do better for this price, and MSI power supplies are generally reliable. If there's one product you won't want to gamble with, it's your power supply, so sticking with a reputable brand works best here.
