I HAVE AN ATI 4870 AND A GT120 running at the same time
OK..this is coming from someone that is actually running both cards..beats the crap out of me how many people can post on a topic that they know NOTHING about. I Installed the GT120 in Slot 3, it does NOT need a power cord. The ATI 4870 uses both of them btw. I powered up the computer with 2 monitors attached to the ATI4870 and nothign attached to the GT120, the computer does NOT like this and will go to a deep sleep after several minutes and won't wake unless you force quit the computer. I then installed a third monitor to the DVI Port ...powered up the computer (now have 3-22" monitors running) and everything has been FLAWLESS since. Everything is great but there is a minor issue of sorts. The computer doesn't like it sometimes if you want to run a high res blu-ray rip for instance across all three monitors..actually it seldom/never works...works beautifully on the 2 monitors connected to the ATI 4870 and beautifully if run on just the GT120...but not across all three...NO BIG DEAL. I like the setup and ordered the card with an education discount for like $134 from Apple. Other than these mega-.mkv blu-ray rips you can work wonderfully across all three monitors ( i can get an adapter and put a fourth monitor if i wish) like they are one.
any Questions???
