I have a SSD and a HDD(not in raid), which will mostly be transferring to other SSDs and I also have the rest of the parts; the current port is only 100mb/s.
I would say excellent, ever since I replaced my 610 for a 970; pretty much max out every game I have, except for my heavily modded skyrim. Only thing I would change is my keyboard because it takes up too much space on my desk.
