yes its a single core but nevertheless he has onboard now without dedicated vram and that seriously acts like a 10 ton weight on the computer performance. With a 6450 he could run oblivion and mass effect, bioshock but now he cant even run Half Life 2.
Also I know that with a 5670 the CPU will be a bottle neck but he can easily upgrade mainboard and cpu later for a few bucks and keep Power Supply and Graphics card.
