I've probably spent around $400 on PSN store related things. $200 on Fifa or even more. The rest on map packs and games that i bought when COD was "good."
2 consoles, 52 games on disc (few limited/special editions), maybe about 10 PSN purchases, numerous DLCs, going on my 6th month of Gamefly, and two years of PS+... so maybe around 3-4K
