I think the parts you listed are fine. If you plan to play only CSGO and other games not graphics crazy.
@cat maybe nightling only does Intel + nVidia combos like myself.
I still have an extra GTX 560Ti if you're interested.
I used to play on a Q9300 but moving to a i5 2500k was a great move imo.
I think it depends what games you mostly play since some are more cpu or gpu intensive.
