The 5670 is rated 60watts max while the 5570 40watts max considering your specs i think the difference will not have a significant impact. The cost diff shouldn't be much, sorry am speculating passively cooled 5570 are more easilly found compared to 5670s

hardware acceleration for video(blueray, flash), better compatibily with softwares,

The only advantage you get from 5670 over 5570 will only manifest during games, if the cost is very important then get the 5570. it would be best not to consider the 5450 because it has a narrower memory bus width and 80 stream processors as opposed to the 5670 and 5570's 400 this basically...

get the radeon 5670 512mb strikes a right balance and uses only 60watts at full load

A geforce 8400m gs is ok because it is well balanced but if u need more power for dx10 games a geforce 8600gt will double the power but drain battery faster

A single one might compete with gtx 280 not gtx260 but when they have it in their x2 config a new born baby 4890x2 vs gtx 285
