What parts should I choose so it can be easier to upgrade while the PC still preforming well

Hey, unicornslayer!

I would highly recommend going with our 13700k motherboard + CPU + RAM bundle kit, as that would provide some of the best value. The 13700k also tends to perform better than the 12900k in games.

That being said, I wouldn't go for a low-end PSU either. I've had success with the PowerSpec branded PSUs in a few more budgety builds, but I wouldn't go super cheap. Just make sure you're going at least 25% above what your computer needs, as that'll leave room for fluctuations. I personally try to go 50% above where I can, but keep in mind we're on a budget. (For example, if your computer wants 500w, I would aim for 750w).

For a budget SSD, I like the Intel 670p when they're on sale (which they are): https://www.microcenter.com/product/636210/intel-670p-series-1tb-ssd-3d-qlc-nand-flash-m2-2280-pcie-nvme-30-x4-internal-solid-state-drive

If we're doing DDR4, I LOVE the G.Skill Ripjaws. Their price has gone down a lot recently, and I've been using them for a while now. If doing DDR5, TeamGroup makes some decent RAM, but I'd probably go for the Ripjaws again if possible.

Still though, consider the bundle if you haven't already purchased a CPU and a motherboard (or if you're still in the return window).

Hope this helps, let us know if you have any other questions :)
