looks pretty good.
and as long as the models don’t get too big. it should be fast.
though 512gb 960 pro for temp drive, and 64gb of ram are probably border line but should be fine 95% of the time esp if your good and clearing temp drive between runs.
I find with 128gb ram that i’m never running out with 2500, but i do some of the time if i’m running cli.
temp drive i regularly use more than 512gb.
I also find the temp drive for rc can’t use more than about 35-45 mb/s. but a hard drive will be really slow. I think it more about response time vs transfer speed. but i guess your looking at QD1 speeds, which is about 45mb/s for a 960. I’ve run this on quite a few variations, from hard drives (bad don’t do it). single 960s, 2 x 950 in raid 0 and 4 x sandisk ssds in raid 0. Once you start using at least a normal ssd there isn’t much of an improvement beyond that. and size becomes more important.
though if you do run out of ram and it goes to swap then the 960’s, and raid 0 ssd’s arrays get much but better speeds there.
