I'd bet a i5 with a HD7670 would crush Trinity in BF3 multiplayer, the multiplayer is BF3 puts a lot of demand on the processor that doesn't show in the single player tests every review shows.
That's good to know. I'd really like to see a Trinity Hybrid setup.
For as many people as there are using laptops as primary computers nowadays there are surprisingly few reviews. The mobile GPU world is a hazy mess of information with model numbers all over the place.
I think I can hold out until the end of the month, if I don't see any new info I'll go with the i5/7670.
