Plenty of NEWER games can work with 9.0c and 3.0 shader and that card beats both of those.

Minimum requirements are
Video Card: DirectX 9 compatible video card with Shader model 3.0.
NVidia 7600, ATI X1600 or better. Onboard GPUs and that 12-pipeline quadro card you have is miles below Nvidia 7600.
That's all games listed just on the steam sale. Pretty much any NEWER indie game will run.
What about Trine 1 and
Trine 2? No way.
I understand the limitations. Older games run just fine on the on-board already as do plenty of non-demanding new games. Just need to figure out if the Quadro would actually help anything.
Then if those games run fine already, why do you even care if the Quadro card will help you?
Imho, the Quadro card is useless for gaming unless you play 2d sidescrollers like Limbo, Braid or Super Meatboy, etc. It only has 12 pipelines and 64-bit memory interface. Also, on-board graphics are pretty much horrible as well.
I strongly suggest you check out both of these reviews to see how budget videocards stack up. You cannot play any popular 3D game released in the last 3-4 years with a low-end graphics cards unless you go all the way down to 640x480 LQ or something:

You should put yourself on the waitlist for this HD4870 for
$55.
If you are on an extreme budget, then there is a
$27 9600GSO, or try to find a GT240 or HD5570/5670 or something along those lines.
If you want people in this thread to tell you that onboard graphics or that Quadro card are sufficient for games, you aren't going to get those answers because we don't really play games at 800x600 with everything on low in DX9.
But, if you feel that your onboard graphics is sufficient enough, just test the games with and without the Quadro card and see if it helps. To us, that would be like comparing a snail to a turtle in a race. Test out both options for yourself and if you are happy with the performance, fine. But otherwise, spend $50 and get yourself a decent budget card so you can play other games, not just 2d indie titles.
