I've got a gtx titan. The main reason for getting it was for the 6gb of VRAM. It comes in handy for games like fallout when you've got a lot of texture mods. My CPU is a 4770k running at stock speeds but I'm planning on water cooling it eventually. The best investment I've made with my computer setup though has to be my 32 inch BENQ 3200PT monitor. 2560x1440 is a beautiful thing.
