What do you currently have that you want to go with new CPU-MoBo-RAM combo?

Do note that $300 is too less for a proper CPU-MoBo-RAM combo for a gaming build.
Though, you can go for these:

This above combo is great for office build though. While you can game on it too but without knowing your old CPU, i can't say if G4560 would be upgrade or downgrade.
