Go analog/pedals:
Get a capable filter pedal - this is the hard choice. There are the classics: Moog MF-101, Lovetone Meatball, Mu-Tron III. All these are discontinued and really expensive, and all these have been copied. PastFX PX-101 is a great version of the Moog, FTElettronica does a great copy of the Meatball (available on Reverb) . . . . there are more, and it really is a rabbit hole.
Octave is pretty simple. Get an OC-2 and call it a day. These are discontinued for a while, but can easily be found, not that expensive either.
Dirt is, yet again, highly specific. Zvex Mastotron is a good starting point for a fuzz that's not that expensive and versatile for synth sounds.
When you go 80's, you need a chorus, too. Can't do 80's without overdoing chorus sounds.
Put them all together and start experimenting. It's a winding path through noisy bushes.
Or go the easy way: Future Impact and/or C4. Both pedals are great, both really benefit from a MIDI controller and both let you customize your sound on the computer, save it to banks and recall it later. The big advantage over regular pedals is that you get ONE synth sound from a pedal chain and you better glue down some knobs because tiny increments of movement can completely screw up your sound. With the digital all-in-one pedals, you recall a preset and it will sound the same every time.

, costs more time (learning), probably the creme de la creme, especially if you're a "synth guy."
