So I bought a second HD5870 videocard, installed the latest WHQL (12.6) and I'm getting 50-55% scaling on Metro in comparison to what I was getting with a single card. In all reviews I saw it easily tops 80% and it often goes as high as 90% performance scaling. Now I've read quite much bad-mouthing for the latest Catalysts in these boards so do you reckon is that it (i.e. the latest Catalysts are pants for older cards)? I'm asking because my install of Windows (7 x64) is fresh and I do not want to mess with the drivers (installing-reinstalling) much; so before moving to any other (former) catalyst I would like to know which may be the best (not just for Metro but generally for 5xxx cards)... Thanks for your time .
