My best bet would be to keep on trying till you get something that suits you well, personally. We don't know your laptop's specs or the monitor's refresh rate, and even if we did, it'd take an IT genius to give you a proper answer without having to buy the same set-up and testing it out him/herself.
I play Warband very smoothly on a 23,4" Samsung Syncmaster monitor at 1920x1080 (60hz), using an AMD Radeon HD6870, Intel i5-2500K and 4GB of RAM. The UI still looks incredibly huge to me sometimes (Mostly the killfeed, I know I can disable it, but I'd just like it to be smaller/only fill up the bottom left half of your screen.), I'd wish there was an option to make it smaller somehow :-\
