go for i3
give you better performance than c2d
yes, dolphin only use 2 core, but windows always juggle non multithreaded (that not using all core) between core never use only 2 core to balance load.
besie, if want dolphin to focus only on 2 core, try lock cores option, or just set dolphin.exe affinity to only 2 core via task manager
just set it on first 2 core (0 and 1), and you'll get dolphin running on 2 physical core (or you could set it on the last 2 core (3 and 4)
so core 0 and 2 run on the same physical core, same goes to core number 1 and 3.
*you get the idea
you'll also can get better result if you get sndy bridge generation laptop.
or get i5 variant (first gen or sandy bridge gen), since it has turbo boost that i3 lack.
i have i5 430M, 2.27GHz turbo boost to 2.53GHz. never bother to set afinity. tatsunoko vs capcom work great
though i'm not really sure how it would scale to that i3

So, there is a possibility to turn off HyperThreading temporarily via Task Manager, are you certain? Please show me a screenshot...
not actually turn off HT, it's still on. but you can set individual process (in this case, dolphin.exe) to run only on certain core
-open task manager
-browse running process
-on dolphin.exe right click and choose set affinity
-assign core

Is that really recommended?
I actually think it's better to find an Notebook with real cores instead, this Hyper Threading stuff makes me uncertain.

so I have to tick 2 & 3 off??

yes, it prevent OS from jugling process between cores. so it prevent dolphin thread being on 2 virtualised core on the same physical core. though from my experience, leaving it be doesn't really matter (doesn't really care actually)
beside, HT meant to increase eficiency per core.
gettwing true quadcore core would be better, buat 2 core with HT still better than 2 core overall.

yes.
if you're not sure whether those 2 core on diferent physical core (not 2 virtual core on same physical core), you can always try diferent combination and bench dolphin.

i thought TS want to get 330M, but that sandy bridge look okay
btw, it is a bit extreme to say sandy bridge mobile 400MHz faster than older gen core mobile. its is faster, but not that extreme. in most case, those bench were meant to test all core.
core i5 turbo boost mode won't kick in with all core, 2.53Ghz on 430M only active with single core.
most of that test still comparing 2.1 i3 SB with 2.27Ghz 430M.
in some sb is faster, and in some 430 still faster. i'd say those 2 are about the same. without factoring turbo boost.
one other merit sandy bridge has over older gen core mobile is higher turbo ratio(which every i3 lack wheter older gen or sandy bridge). most 1st gen core mobile only get extra 2x multiplier on turbo boost, while SB get 4-5x multiplier on turbo boost

Benchmark list
lol, i'm not gonna argue about sandy bridge being faster at same clock rate, i agree with you on that matter.
what i meant to say in my previous post, when comparing 430M and 2310, there's potential with turbo boost on i5 series, since dolphin only use 2 core max. though how much, i can't really say (if there's any) since no one actually bench dolphin using both cpu and post result. i tend not to rely much on synthetic bench. especialy when i want to know how it compare when using emulator that rarely use more than 1 (in this case 2 in dolphin) thread/core.
ehm, i don't know why i even comparing it with sandy bridge, i actually skimmed post on first page
only read that TS want i3 330M, that's why i post 430M result.
