And does Internet speed affect fps? And could it run bf3

 

You should have no problems running RuneScape at high detail, to be honest you could probably max it.

As for BF3, I imagine you should be able to run it. As for maxing it, I'm not sure on the GPU as I don't do a lot of ATI. However the rest of the parts seem very good.

Also, Internet speed doesn't affect FPS, although without a good Internet connection, you may find you will lag during online games and such.

 

As laptop said, you should have no problem. RAM VID and CPU are all fine for runescape. Playing bf3 on a decent quality will be tough for that card though. Everything is fine, just look at upgrading your Video Card.

 

Runescape @ 50 fps for sure.
