If i get a trple sli board and added 2 low end cards will they combine, and if so will it work using one monitor or 60inch tv as your monitor. I am a little confuzed about crossfire x and sli. I was thinking why not add 2 low end cards and get the same performance as one high end card but i heard it dosent do any difference (if you don't have 2 monitors) its best off buying a high end card is he telling the truth please reply thanks in advance.
