Your CPU should have no issues running these games, its the best there is for Dolphin in a laptop. Seconding what DJBarry said, post your graphics and config tabs from Dolphin here so we can see what the issue might be.
Make sure windows Power Management is set to High Performance, your computer is plugged into power, and under Nvidia Control Panel you have Dolphin set to use the high-performance card and maximum power (DON"T SET THROUGH DOLPHIN, YOU WILL GET ERRORS)
You can overclock the 4900MQ just fine up to 4.3Ghz on a single core and 4.2Ghz on all cores.
Although it is Turbo boost it is trivial to change settings in XTU so it keeps using the max clock at all times, of course you may be limited to your TDP (for instance Alienware 18 have a 330W PSU, so you can't get over that limit (globally speaking), your CPU may also overheat at high frequencies (like 4.2Ghz on all cores)
You can reasonably get to 4.0Ghz on all cores without even modifying the CPU voltage while still not throttling, at least on the AW18, on the AW17 you might need to change your PSU (it comes with a 240W by default, 220W on lower GPU configurations) to a 330W, the cooling system, although state of the art, in the AW17 is still not as efficient as on the AW18 where people can reach 4.5Ghz using 4930/4940MX CPUs !
I am not even using 4.0Ghz (although I am overclocked, 4Ghz one thread, 3.9Ghz 2 threads) on all cores and I get full speed in Fzero GX (when the game doesn't crash), Mario Kart WII (except in menus), Zelda Twilight Princess (even in the hyrule field with the ZTP hack), MGS TTS and so on. All that is of course while using 2xSSAA and 3x Internal resolution (I could set it higher but I don't see any differences, so what's the point in wasting resources?), oh! and it's all running using LLE rather than HLE.
On previous builds (the ones allowing the DX9 backend, I can even play Fzero GX at constant 60fps using Stereo 3D (3D Vision) !
Depending on your build you should be able to run the most demanding games, in fact I haven't found an ingame situation when I dropped below 60 or 30fps (depending on what the game is locked to) which on a laptop is truly amazing. I haven't tried other demanding games like the last story though.
(I am using an Alienware 18 with an intel 4900MQ CPU, 32GB of RAM (I am actually using this a lot with vmware !) and a GTX880M SLI setup (yes, I know that Dolphin can't make use of the SLI), I also run every dolphin games from a SSD RAID0 array, so that may limit some copy to texture issues)
Oh! and Obviously my GPU is set to performance rather than adaptive in the Nvidia control panel, not that it changes much since I still average at 45-50 fps on Dolphin after switching to the Intel HD 4600 GPU. (yes I actually tried that xD)
