New pc, New boxer, new ideas?

So I have been tooling around with this idea for a bit, and I final decided to go out and build my first PC. This thing is a beast, and I am currently running two screens. A 17inc and a 24. I have another 17inc sitting next to my big 24, but I have no idea how to hook it up as a third screen, considering my video card only has two outputs. I know my system can handle it, as it is top of the line, I just dont know what hardware I need to connect a 3'rd screen to my two port video card. Links/ideas anyone?

The easiest solution is get another videocard.

Well that had crossed my mind, however I don't want to add another video card, as the best was would be to double the video card I have now, and SLI them together. but this causes a problem because my motherboard has 4 slots, two of which are being used by the 8800 and one of which an Ethernet converter. I would have to add a single slot video card, and then I could not SLI them together. I would be running one wow off of a lower end video card and two of my powerhorse. I was looking for some sort of screan spliter? or something of that nature, as im not even sure that exsists.

Not possible and iirc, wow is not optimized for SLI and you will have terrible performance if you use it that way. Get the single card, and run the 3rd monitor off of it. Thats the only way to accomplish this. A screen splitter ain't gonna do shit for ya.

IIRC?

If I Recall Correctly

Well I did some brousing and I found out about the Matrox Tripplehead2go, but I dont have the extra 300 bucks to fork out for this, so is their any cheeper hardware? Or is this a "ya get what ya pay for" kind of thing? My video card can handle 2 as it has two outputs.
