A few things to keep in mind..
17" to 19" LCDs use 1280x1024 resolution, so while a 19" LCD is bigger, you're not getting any more screen area vs a 17", you're simply making the pixels bigger.
Now for some people 1280x1024 is too small on a 17" LCD and prefer an 18 or 19" LCD at that resolution. Others don't want to waste the extra $$ on simply a bigger screen, and opt for a higher performance 17".
Also the 912N doesn't have a digital input, only analog. Not a huge issue at 1280x1024, but out of the ones I've tried I prefer the digital interface; there's a visible difference. I have computers set up with dual 19" LCDs at work and the left uses DVI and the right uses analog, and you can tell the difference.
At work I went through five or six different 19" LCDs before deciding on a few models. I've got a 912N on the server; it wasn't up to snuff for gaming. The 25ms response just doesn't cut it. Since you only have a GeForce 2 card, gaming isn't going to be an amazing experience anyway, so it might not be a big deal. FS takes returns, so you can buy it and try it, and return it if you don't like it.
As for the models I decided on the Sharp:

and the Benq FP931 for $584 after rebate:

The Sharp looks very nice and games quite well for a 16ms screen, though only having analog inputs hurts it a bit.
The FP931 isn't quite as good as the Sharp, but for the price was far and away the best value LCD I found. It has a digital input as well. It's 16ms as well and games nicely, though not as good as the Sharp IMO.
You might also check out the Benq FP937s-D for $679.95. It has a 12ms response and a 500:1 contrast ratio. I never got a chance to try that one, but the specs look good. Usually though the faster the LCD the "fuzzier" the picture.

(Better price at Memory Express)
If gaming and movie playback are very low on your list though, that Samsung has a 800:1 contrast ratio and looks extremely good in Windows.
Hope that helps more than it confuses
