3 Graphics cards is a guide? :S
all AMD, that's just disappointing.
No benchmarks to justify the choices as well.
I don't think there is anything wrong with doing things this way, and maybe the only reason I do things differently is because I've been poor all my life. Anyway, the way I do it is I always find whatever option gives price to performance ratio. There is always a sweet spot on the market, though sometimes it is not so well defined. The sweet spot is the point at which if you continue to spend the same amount of money more than a cheaper model you don't get the same increases in performance. TThat's how I roll...
CPU: AMD PhenomII Quad-Core 3.2GHz
RAM: 2x2Gb ddr2-1066MHz

Yes, interesting, BUT, what about the pricier cards R2000 to R5000?
And NOT just AMD cards. How about some Nvidia cards.
