How do I use 2 Monitors at once?

I just bought a lovely 22 inch Samsung lcd monitor today, its amazing, and i dont get my harddrive back for another week (it%26#39;s being replaced) but i wanted to prepare for when it does so i dont have to ask about this then, ill already be ready for it. im wondering how to set up dual monitors.i have this 22 inch lcd, and a 19 inch crt monitor. is that ok? theres 2 slots on the back of my vid card for monitors, so im guessing the 1st step is to plug both in, but of course the screen will still be on my monitor that ive been using, what do i do then? how do i set up so both monitors are used? how does it work? how do i move one mouse to the next? how do i play a game on one monitor and use aim an internet on another? can both use dvi cords with an adapter to fit on my 1900gt? please give me a detailed step by step way to do this! thanks for the help, im excited to be able to do this.
also, by having dual monitors, is it going to take up move power from my vid card, as in will it work my video card a lot harder than usual or will it not really matter? will it work my cpu harder or anything else? thanks! How do I use 2 Monitors at once?

If you are using two desktops, then your vid card will be more stressed. If you stretch your desktop over the two monitors, it will not be stressed more.My 7900 GS comes with dual monitor software. It is nvidia however, i dunno how a ati works over 2 monitors though. 
ok a couple of more questions now that i know how to set it up. if i select expand window or whatever, itll have like 1 desktop over 2 monitors and when you maximize a window itll take up the whole screen of the monitor your mouse is in right? that way aim and email or internet can be in one monitor and a game can be the other right? that way a game isnt on both monitors or half on 1 monitor and half on the other right? also, can you set a button to move from monitor to monitor that way you dont accidently move your mouse to far? thanks for the help

When you expand a window, it generally expands on the monitor that your mouse is on, but some application have little bugs that wll expand them only on the primary monitor. You can also do an extended desktop set up so that when you expand a window it goes over both of the monitors. It%26#39;s a little weird that way but some apps do benefit from that. 2. Yes, you can have a movie playing on one screen and AIM or a browser on the other. Convenience at its best. ;) 3. Playing games on dual monitors isn%26#39;t the best idea unless that game supports dual monitors. The thing is that sometimes the mouse doesn%26#39;t get locked into the one screen so your mouse can go onto the other monitor and you%26#39;re gonna have problems turning in FPS or moving the screen on some RTS games.4. You move from screen to screen by just moving your mouse past the first screen. You%26#39;ll see what I mean when you set it up. I don%26#39;t know if your dual-monitor software is a little more feature-rich than the one I have but I don%26#39;t get that option so I don%26#39;t know about that. Maybe you can find some third-party software. 
i would never have a game on more than one monitor, so as long as i do that, my video card wont work any harder?thanks for your help, and how likely will my mouse roll over to the other by accident when playing a game?
