I want to play
And
And the upcoming Starship Troopers extermination game
I want it to run smoothly but I don't know what sort of good custom PC to buy. My dad told me the ones on BuildRedux are a massive rip off and I can get a "good" one that is on par with the BuildRedux PC's for half the price of their cheapest option.
Ugh, both are kinda crap and their resource requirements are not that high.
I could run Grey Goo on a pretty old desktop years back, 2GB 270X ATI card and an AMD 8350.
And Terran Command is not that good looking and I don't think you'd need more than a low end to average videocard.
Make sure you get at least 4GB of GPU RAM with all the latest fancy shit and a decent AMD cpu, 6-8 cores, I think the more recent midrange Ryzen.
I would recommend at least 16Gb of ram and don't be stingy for where the PSU is concerned, Corsair produces both and the ones I bought back when I cared about building my own PC rather than buying a gaming laptop were decent.
There are classes of PSUs btw, look at sliver, but bronze which is budget is OK, too.
Cooling, make sure to get some decent cooling, I like CoolerMaster.
Mobo - very important to not disregard this, I'd go with AsRock, since they are a decent, performance brand and not that expensive vs, Gygabyte IIRC.
Just make sure it can handle your RAM and CPU at optimal speeds and that your PSU can provide enough power for everything, also, usually the Gaming models are more expensive and come at a premium, so look at the more budget ones first.
Once upon a time there were a few calculators that would give you PSU spec recommendations on the basis of your other hardware and peripherals and then tell you what Wattage PSU to get.
And most importantly, I/O make sure to get a decent SSD or NVMe drive or several, load times are significantly better, RN they are not that expansive, but get a reliable brand that doesn't defect as much.
I'd look into WD, hynix(my current laptop's NVMe), and maybe Seagata, I am still salty at Seagate for one HDD I had that crapped out back in the day.
Since you will have the sace you can put in one good quality NVMe(128 to 256 Gb) for the OS and the essentials plus a few regular SSDs of the cheap ass 90$ or below variety for stuff you can afford to lose, like game installs and the like, prrovided it is not something that has to load huge amounts of data very fast, like the truly massive games, yu can also look into an HDD for bulk stuff, like photos, 7 seas bounty, older games.
Truth be told, I play most of my games off of a chinese SSD in an USB enclosure and I rarely feel the difference, but I have 32 Gb of Ram, too, so ocne shit gets cached there is little problem.
The case - get something BIG!
My old one was iirc thermaltake, just make sure you have enough fans and it does not make problems with airflow.
