the intel stuff you posted is junk!
did you search switchable graphics as suggested ? ( google ) http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CDIQFjAA&url=http%3A%2F%2Fwww.amd.com%2Fus%2Fproducts%2Ftechnologies%2Fswitchable-graphics%2FPages%2Fswitchable-graphics.aspx&ei=30UhUaGyDrSP0QGd4YHwDA&usg=AFQjCNF3m55fRkONoc0dGSgBbbnZ2a57mw&bvm=bv.42553238,d.dmQ&cad=rja
there are also intel based laptops with switchable graphics. but until you do a lot of reading and familiarize yourself with the hardware and what it can do, you will be tossing money away.
It isn't just " i want to buy a laptop".
did you read above about the AMD APU? do some research ( again, google )
the apu ( in a new laptop ) would be the best bet under your circumstances)
don't buy junk that will be no better than where you are now.
