260 speed with neutral nature -> 286 with speed boosting nature
260 speed with 15 IVs -> 276 speed with 31 IVs
260 speed neutral 15 IVs -> to 31 IVs with boosting nature (260+16)* 1.1 = 303.
To most people the difference between the 286 and 303, (as dusk said) will be almost unnoticeable. It's only if you're competitive battling and are worried about base speed ties that you really have to worry. But for the average person, you really don't need to worry about IVs.
