Not much of a review, but this one's more of a cheaper setup - instead of using th3 $100 DP (active) adapter, you can get a 30$ passive that works. i use the same adapter in this setup/review, and so far no issues.
This adapter is just a Bizlink passive display port to VGA adapter that is released by HP. It's about $30. You can get them as cheap as $20, but I wanted one that I knew worked, and it's well documented that this HP adapter works perfectly. I got mine from CostCentral, it was $28 there. The part number is AS615AA. You can find it in a lot of different places. Just search that number and find a place with free shipping or a low shipping rate and you're golden.
This one's more of a review, sort of, but it has benchmarks and screenshots of some nice games.
I used these two places to convince me that i should get into the eyefinity setup...and i am glad i was able to finish it before my job's hours were cut.
