Should you be worried about 1, 5, or 10 ms of input lag? Use Latency Split Test (LST) and find out!

if I do decid to cap it do I turn of reflex? Or leave it on with the fps cap?

Reflex is the automatic version of a manually set cap, so you don't need both. I.E. only use a manual cap to prevent max GPU usage if Reflex isn't available.
