More expensive not because it run faster, but because it could be run at much lower voltage, and not all the chips coming off oven can pull it off.
3210M is running at 35W at 2.5GHz normal. When Turbo kick in (CPU under load), it go up to 3.1GHz.
3317U on the other hand, is running at 17W at 1.7GHz normal. When Turbo kick in, it go up to 2.6GHz.
So if you looking at top speed, 3210M win. But 3317U is running off 50% the power requirement (not so directly translated to real world performance since CPU only represent part of laptop total power consumption)
More over, 3317U can go down to 14W when idle.
I will take the best 2nd gen i3, i3-2370M as comparison. It run at 35W at 2.4GHz, and no Turbo available.
And the IGPU HD4000 in i5-3317U is so much better than the HD 3000 in i3-2370M.
Yes, BF3 at HD resolution is playable in K46CM. But being skinny, it don't dissipate heat that well, you better get good external cooling solution to prolong the life of laptop

Wow..your explanation very useful to me..
So there is no problem to playing games in aircond room + cooling pad using k46cm no matter if you play for 24hrs?
