I suggest getting the 5700x3d, generally costs $260 and has pretty much same performance as 7800x3d in DD2. Even though the platform is at a dead end, this is still a high quality CPU and much more value than an AM5 CPU right now.
Heres a little mockup:
CPU: Ryzen 5 5700x3D ($258 carousell $200 taobao)
CPU Cooler:Thermalright PA120SE ($48 amazon)
Motherboard: MSI B550M PRO-VDH Wifi($160 amazon, use DBS card for$15 off) 2 SSD slots / ASUS Prime B450M-A II (1 SSD slot but $99)
RAM: Lexar 16GB(8x2) THOR DDR4 3200Mhz ($37 amazon)
SSD: Samsung 990 Evo 2TB ($162 amazon)
GPU: ???
PSU: Thermaltake GF1 850W $147
CASE: Montech Air 903 Max $70 carousell, includes 3x140 fans
This adds up to $867, which you can spend around 1k for the gpu. However, new AMD/NVIDIA gpus coming soon, could release before MH Wilds come out. PSU/Motherboard pricing probably could be better, but this is the best i can find.
I think I really want a 4070 super/ti but would it be wiser to wait for the 50 series if not in a hurry or is it better to grab the 40 series now as they're being discontinued and could get more expensive?2k is plenty for a decent cpu + gpu, especially if u buy prebuilt. right now u can get a 7600 + 78xt from invaderpc for less than 1.3k, which can do 4k gaming quite well and u will be set for the next few years. u can consider faster parts like the 78x3d or 4070 super, which are considerably more expensive but both can still be fit within 2k.
am4 isnt worth it for builds costing over 1k, and the 57x3d is only really for those already on am4. depending on the resolution, cpu may not matter as much, even in cpu bound engines like ue5.
i would go for a local set adata xpg core reactor for $20 less.
price and flexibility. invader pricing is pretty good, most of the time u diy also cannot beat, but u lose the choice in picking the exact parts u want. going to dynacore is the exact opposite, but thats not to say one is better over the other.
then u really have to diy or go pc shops, including cleaning the pc or just suck up the cleaning cost. most system integrators have a very limited selection of parts compared to diy.
