I wouldn't expect performance to increase linearly to be honest, other factors will come into play. E.g. what raid controller are you using?

The one on the board it was told on linus tech tips forum i would need a dedicated raid card because it does scale pretty much linearly. In that cas I am just going to trade it for ram or a gpu.

You're not going to get 750 performance with 3 SATA SSD in RAID. The performance comes from IOPS, not sequential speeds. Also, you won't see a difference either. Memory bandwidth isn't high enough on AMD platform to really benefit from a speedy OS being driven by a PCI-E NVMe SSD, and the SATA solution on motherboard RAID won't come close.
