If you were in my shoes, what system would you pick? Seeing as Im currently only playing LoL.. any of these systems will be more than enough, however.. there is a slight chance I might play something like WoW in the future.. however, just a slight chance. Should I got for one of the 700 systems or will the 600 euro system be enough for medium / high settings in games such a WoW?
#1 one will do everything you are mentioning and should be upgradeable in the future should your needs change. GTX650 is great for playing slightly older games at high quality or the newest ones at lowered resolution.
