I've recently been playing quite a bit of Syndicate Wars on the PC (amazing game, go play it!) and at a few parts of the game when it got really tough i did read a couple of guides, but also looked on YouTube and found nothing at all really. Quite surprised i didn't even find anything on the great Longplays channel. So basically I'd like to be able to record me playing the game so I can upload the videos to YouTube.
Whats the best software to do this at the moment? Also will my PC specs make a difference to the video quality/game performance (i know its an old game) My pc is a AMD 7850 BE (2.8ghz) 2gb ram and 8800gts.

thanks
