I'd say not worth it. The 6450 is beyond low end, mostly for a dual monitor setup on a budget, those APU's have pretty killer graphics on their own, i'd say either go with an FX chip and get a discrete card for all your graphics needs, or throw all your eggs in the APU basket and save that money for some other fun upgrade. I run AMD CPU's and Graphics, but i must say that the crossfire stuff doesn't work super well in most cases in my experience, which is what you'd be doing.
