Upgrade from Llano

My brother is running a Llano A6-3670, he wants a graphics upgrade to play something like bf3 at good frames with at least medium presets.

for the best frames:money ratio what would you recommend for a £130 budget? ($200) new apu, hybrid xfire or something like a gtx 560?

thanks

 

xfire

what cards can be crossfired with it?

okay so will the igp + a £60 6670 perform better or worse than a £100 card non xfire?

prolly better....

not sure how xfire works, but if you set the discrete card as the 'primary card', it will probably be alot better.

and btw, really fast ram helps the apu's considerably

k this seems like the right path, thanks for the help
