I'm putting together a black 1440p gaming PC and would like a final sanity check before ordering. The planned parts are a Montech XR case, Ryzen 7 7700, Gigabyte B650 Eagle motherboard, DeepCool AG500 cooler, 16GB of Patriot Viper Venom DDR5-6000 CL30 memory, a 500GB Kingston NV3 SSD, and a Montech Century II 850W power supply. I'll buy the graphics card used and choose whichever deal is best among the RTX 4070, 4070 Ti, or 4070 Super. I know 500GB is limited, but I'm fine adding more storage later. I may also upgrade the RAM around Christmas, although I'm unsure whether mixing another kit later is a good idea. Does this look balanced, and would a newer Ryzen 5 9600X be a better choice than the 7700?

The overall parts list is reasonable. The 850W power supply gives you plenty of headroom for a used RTX 4070-class card, and the AG500 should be adequate for either processor. The 500GB SSD is fine as a starting drive if you genuinely don’t need much space, though check reviews for the exact NV3 version and consider a larger TLC drive later for a game library. For the GPU, prioritize condition, warranty, price, and cooling over the specific 4070 model; DLSS is a valid reason to stay with NVIDIA if the competing cards cost about the same.
The biggest concern is the memory. One 16GB stick will run in single-channel mode, which can noticeably hurt performance in some games. If possible, buy a matched 2x16GB DDR5-6000 CL30 kit now. Adding a second kit later may work, but even identical-looking kits can use different memory chips or struggle at their advertised speed. If 16GB is all you can afford, use it temporarily and replace it with a matched 32GB kit later rather than counting on a perfect upgrade.
The Ryzen 7 7700 is still a good option, especially if you’ll do productivity work as well as gaming because it has eight cores. If this is almost exclusively for gaming, compare its price with the newer Ryzen 5 9600X—the 9600X can offer stronger gaming performance and a longer upgrade path, but the 7700 is not a bad choice if it’s significantly cheaper.
That makes sense. I’m leaning toward the 9600X now since this will mainly be a gaming system.

I can’t fit 32GB into the budget right now, so I’ll probably use 16GB temporarily and replace it with a complete 32GB kit when I need more.
