I have no clue about how FP works but I think the gpu is more important looking at loading bar.
I could tell you this for sure after moving from a a gtx1050ti to a gtx1080 but the gtx1080 is also on a much better motherboard and cpu so...
Anyway, FP is old and ineffective so I personally don't expect miraculous load times. I need to try this on a recent pc with much better hardware I also own but I can tell you it's not worth the price even if it loads instantaneously (it won't)
