If you're in the market for a new PC build this Prime Day, doing all the legwork to find great parts that are on sale, in stock, and compatible is tough work. We've done the hard stuff for you and compiled a PC (mostly) built using parts on sale at Amazon Prime Day. The result? A $1,600-ish build (including a Radeon RX 9070 or RTX 5070) that won't break the bank but should give you excellent 1440p performance.

Of course, there's no pleasing everyone with a PC build, so take this as a guideline. We built around the still-spectacular Ryzen 7 7800X3D CPU, but there are Intel processor deals to be had out there, too. You can tone down (or up) the motherboard, add a beefier SSD, or choose a slightly less jazzy cooler in the name of savings if you choose. With that being said, here's the rundown of our parts and the build.

$1,600 Prime Day gaming PC: Quick list

This chip is among the fastest gaming CPUs on the market and drops into modern AM5 motherboards. It's got 96MB of L3 thanks to AMD's explosive 3D V-Cache, eight cores, and 16 threads. It also features a maximum boost clock of 5.0 GHz.

Thermalright PS120SE CPU Air Cooler
Thermalright PS120SE CPU Air Cooler: $35 at Amazon

We don't need an AIO for the processor here, so an excellent air cooler should suffice. If you really want the aesthetic and overkill of liquid cooling, you can add an AIO, but a decent one will add $50-$100 to your build.

ASRock Challenger Radeon RX 9070 16GB
ASRock Challenger Radeon RX 9070 16GB: $599 at Newegg

Surprise, if you want a great GPU during Prime Day, you probably shouldn't shop at Amazon. This RX 9070 gets a nod over an Nvidia card thanks to its great 1440p performance in our review. At $599, it's just $50 away from AMD's MSRP. It also sports 16GB of VRAM, and boost clocks of up to 2520 MHz.

If you really want an RTX card from Nvidia though, try this:

MSI Ventus 3X OC RTX 5070 12GB
Save $90
MSI Ventus 3X OC RTX 5070 12GB : was $619 now $529 at Newegg

If you'd rather go with Nvidia and DLSS 4 tech, this MSI Ventus 3X OC RTX 5070 has a straightforward triple-fan cooler design without any frills, but what more do you need for gaming goodness?

After a $20 rebate from MSI and $70 back on a Newegg gift card, this card is effectively $20 under Nvidia's $549.99 MSRP. It's one of the cheapest RTX 5070s we've seen.

    Not a bad system but I think I’d consider looking at a b650 or b850 board and a 7700x or 9700x cpu and then see if that allows enough budget to bump the gpu another level.

    You put together a $1600 system, but with this power supply, how long will it last?

    I think the GF1 is A rated iirc. I have a 1200 watt in my rig. But with the vanilla 9070 i think you’d have a little less power draw.

    This ^

    I was thinking the exact same thing when looking at the parts list. Not a bad system at all, but I would scale down the chipset, CPU, and prioritize a bump up in GPU (even though an RX 9070 and 5070 are fine in their own right.) Better investment for anyone who doesn't want to fight over the next generation of GPU's and they could always do a drop-in upgrade on the CPU later, which would be less of a headache comparatively.

    The other thing with CPUs, I’ve got a 7700 non x in my own pc paired with a b650 and a 9070xt. Sure a 7800x3d would be nice but what would I get out of that? Maybe slight improvements in 1% lows? Sure if you’re a competitive gamer playing multiplayer all the time the x3d CPUs have some benefit, but for your average gamer playing the latest single player AAA games and dabbling in multiplayer, bump the chipset and cpu down for a better gpu and you’ll likely notice more performance in those circumstances.

    For example though, the 7700x can be had on amazon for $215. One of the cheaper msi b650 boards is $129. So you basically save the cost of a board. That leaves a lot more room for a better gpu, psu, storage or whatever you wish. Just my 2 cents.

    I'd stay away from asus mobos, especially expensive ones.

    This is a solid build for that price. I would probably go for one of the MSI Pro B650 lineup MOBOs instead of this one and it still comes out at the same price of 569.99 (bundle currently available at Amazon).
