rev 1 of lightpeak is crap, it lacks proper bandwith.
hd 3000 is NOT as good as 320m, so you will se a fps decrease.
the benchmarks show 320m up to 50% faster then with a sandy bridge i7 quad core with a hd3000 igp.
So get your facts straight
I suggest you take your own advice. The HD 3000 (with a quad core, granted) is faster in many games.

The average of these benchmarks shows the 3000 is faster as well.
