I'm building a PC. I'm trying to get good performance with Star Citizen. My current (basic) list of stuff:
Intel 900P Optane SSD (280GB)
Intel i7-6700K
GTX 1070 TI
Ripjaw X 16GB RAM (2x8)
Would that run SC, and is that a halfway decent build or am I failing miserably? I've never actually built a PC before :3
First of all, if you already have a PC that can run SC 3.0 in the Universe at 15-20fps, don't expect any benefits from a new machine! The problem is not on your end. If you can wait with a new build, than I'd suggest you do, until the game gets more optimized and new hardware comes out.
That said, if you want a good PC, you are on the right track for a great machine.
Optane feels like total overkill at the moment, a basic SSD would be just as good for gaming, for much less money. If you don't mind spending so much money on something that currently has no benefits over a simple SSD, but is future proof, it is a good choice!
i7 is nice! For SC in the long run, going for 8 or more cores is supposed to improve performance. I'm no expert on processor versions, so I can only tell you that it runs perfectly fine at the moment on my "old" 4core 4670K. I'm sure someone else here will point you in the right direction for which generation of processor to go for.
GTX 1070 TI is an interesting choice, as far as I know it's pretty damn good in price/performance! The important question here is, what display resolution are you aiming for? HD, 4K, 3x8K monitors? :D
RAM! Go for More RAM! If you can afford it, go for 32gigs, I heard it improves performance in SC a lot. I got 16gigs and it runs fine, but more RAM never hurts!
