Kurtiskain, that's wrong.
The E5200 is part of the Core 2 Duo family, and the E7300 has a faster clock speed and some more cache.
s-mac, could you explain how your CPU is similar please?
And computeruler, how do you know that CPU will not be able to handle games maxed out? You don't even know which games he's planning on playing. Also, some of us work within budgets, so going for the fastest CPU available isn't an option, which seems to be what you're suggesting - your post did confuse me though.
