No for Mass Effect 3. Pretty sure a no for SWTOR, but I don't play it.
I tested Mass Effects 1 on a laptop with a Core i5-2410m and using the Intel HD 3000 graphics core instead of the dedicated video card. The Intel HD 3000 is basically equal to the Radeon HD 5450 without DX11. That is a little more powerful than your video card.
There was a lot of dropped frames when simply walking on the bridge of the Normandy (the frigate that you eventually command). Simple combat with only a few enemies in the 1st mission had a lot of stuttering.
