I am looking at Sapphire HD 7770 1 GB GDDR5.. maybe would need 2 of these i believe.. for 6 - 8 monitor setup.. I am thinking for I7 3930K now.. just few bucks difference .. and than i do not have to run again for few years to build a system again..
am confused, if you are going for 6-8 monitors... how are you going to get that with that card? you should look instead at the following if you still plan to stick with your current path.... ASUS HD7970-DC2-3GD5 Radeon HD 7970 it will provide you with 4 DisplayPorts and 2xDVD-Ds... so 6 monitors total...and I like their cooling design... I have their 650Ti model.. as to the monitors, I havent used Asus, but their cards have really good reviews..
Half of what was said about monitors would have been skipped had you stated this earlier. Until, everybody thought you wanted to build a trading rig. Light gaming? Power gaming? (Just about any modern video card will play movies just fine.)
