All 3 of those can run Crysis fine on medium settings based on customer reviews. Running Crysis is just a bonus really since I'll mainly be playing CS:S and FFXI on my laptop. I own 360 for the higher end games and I'll eventually get PS3 for Blu-Ray once the price drops.
I think I'll decide between 2&3. Is there a huge difference between Core 2 Duo P8600 and T6400? It seems like option 2 has a better CPU but lesser graphics card than option 3? Hmm anyone have experience with the new GeForce GT 1xxM line?
