And what comes to your setup, it's still pretty relevant in terms of performance, only downside being your setup is locked, hence overclocking is limited to basically 0. That said GPU might be the only real upgrade if you play something else than LoL or WoW, but if you only play LoL and WoW, your current GPU is good enough.
Clean install means just formatting your Windows partition and Installing Windows again. As to what SSD, Samsung 850 Evo is quite decent. It's quite good value even when not on sale, but it's on sale quite often. And how big to get, 250GB is enough to run Windows and some games, but you really won't see much performance upgrade in games outside loading times being reduced.
