I agree. Actually for the present generation games, it is more than sufficient to play at the highest settings, except may be Metro 2033, which I don't have. Crysis 2 with DX11 was OK on my C2D, so with a better CPU, you are bound to get good performance at FullHD res.
And regarding OC, well atm you don't need to.
