You may want to check with the tech support from the vendor who sells this kind of software on this question. I used to use Camtasia to record my trading session. TradeStation charts. I had 6 x 19" monitors on my computer. But I decided to record only 1.25 monitor worth of screen space. Camtasia took it over up to about 2 hours of recording. Anything beyond 2 hours, it took forever to finish the recording on the disk (like waited for 8 hours and still not finished... I ended up aborting). Subsequently I had to break up my recordings into about 1 hour to 1.5 hour each. And I needed to trigger the recording-start multiple times througout the day. Your config for 4 x 24" screen space, and up to 6.5 to 7 hours of recording each day... I have doubt that it can be done. The graphics card would probably be irrelevant. But you may not find a fast enough CPU to process the information, and a disk drive fast enough to record all the data, and large enough to contain the data generated every day for a good period of time. My Camtasia recording files (1.5 hour worth) were about 100MB each, something like that. So 1 day would be 700MB. 25 days would be 17GB. That's on a resolution of only about 1900 x 900. It can't be generalized easily because their screen capturing software may have ways to reduce disk usage. The best is to get a trial copy of the software and do some actual recording on smaller screen space, then extrapolate.
