Firestrike does factor in CPU performance pretty significantly, so you have to compare it to similar CPUs, you also have to compare it to ones with similar GHZ/MHZ to yours.
what kind of benchmark score should i be getting in firestrike in 1080p?
i feel like the money i've spent on my computer i should be able to run games like assassins creed on ultra way above 60 fps?
I don't run benchmarks on my SLI 970s but I can tell you it's probably the game. Assassin's Creed Unity didn't run very well and apparently Syndicate isn't that much better. Try other games before you get upset with your new system. Also, what CPU are you running? CPU was the limiting factor for most people in Unity since there are so much AI NPCs on screen.
