Those LGs only work with AMD cards. What do you have? If you've got Nvidia in your box, you should get a set, a monitor that comes with Nvidia 3D Vision 2 glasses.
Also, you need to have a decent setup overall if you want to take advantage of 3D, mostly because your perceived framerate will be cut in half. If you want an apparent 60fps, you'll need to be rocking games at 120fps on whatever low settings or on whatever fantastic GPU (or two) it takes to make that happen.
There are advantages and disadvantages to both Nvidia's and AMD's proprietary 3D technologies. You can check them out in Tom's review from last year here: http://www.tomshardware.com/reviews/geforce-3d-vision-hd3d-steroscopic,3050-11.html
I don't know how many of the software issues have been ironed out at this point, but you can generally check game compatibility, at least, on the Nvidia and AMD websites.
