u m isn't that kind of self explanatory? ill go through it any way though, you can use your hardrive as the graphics card (well kind of i guess just a really crappy one, it will skip lag half life 2 for example that's why i had to buy a new graphics card since running things off of the hardrive doesn't work that well)so that's what i meant i only was saying one of my past experiences with having no graphics card, so you can run trem with no graphics card, well your comp has to be half way decent though..
