Bart,
Welcome to the forums! I am not that familiar with Map Point's drawing but I may be able to lend you some insight into Map Suite. You question is a bit open ended as with performance so many things matter. For example if the polygon has 10 or 1000 points, what kind of specific atom processor, how much ram, how much ram is free, if you use allot of disk while drawing etc. I think the best way is to try it out and see what happens.
Of course you mention you wanted a sanity check first so I will try my best. I am running righ tnow on a few year old Thinkpad and we have a sample application called "Refresh points Randomly" and in the sample you can choose a refresh rate and number of point along with some other stuff. With my machine i can pretty easily do 1000 random point changes in 300ms. At 2000 points at 300ms intervals it starts to lag behind. Of course these are 1000 or 2000 points in view. If I zoom in a bit and we still have the 2000 points but I can see less then the perf is better. On my desktop machine at work I can do allot more.
My suggestion is if you are still not sure is to dowload the evaluation, install it. Then under the start menu and ThinkGeo\DesktopEdtion we have an application called "Winforms How Do I Samples" This is a pre-compiled version of our samples. You then just open the tre view node "Dynamic Shapes" and click the sample called "Refresh points Randomly" This way you can test it on your atom machine without needing Visual Studio or anything, it is all pre-compiled. This also refreshed the points over a map of the world.
