You're not likely going to find a video card that will work with that PSU and push your screen.
Thanks for the reply, that's helpful as I wasn't even considering ATI and they were outperforming nVidia when my PC came out. I don't expect to push the monitor's capabilities on this system, I'm just thinking about leveling it up on the cheap until I can swap out the system entirely. I've got about three months to Spore, and six to Starcraft 2, so those are my deadlines
