First generation i5 vs 2nd generation i3

[Barbs]

I am looking to get my kid a home laptop - usual office, web and light gaming. But I would like to get the best bang for buck.

For the same money I can get a:

1st gen i5 (i5-2410M)
Or
2nd gen i3 (i3-2330M)

My money is on the 1st gen 15, but I would be keen to get some opinions.

Thanks,

Kieran.
