Video Card Choices

Hello,

I just registered on this site and need a little advice on upgrading some things on my computer. I am looking to upgrade my video card from the current NVIDIA GeForce 6800 XT (256 MB). I have an older system though I have upgraded it significantly over the years. My current system is a Compaq Presario SR1810NX Desktop PC. I upgraded it so its current stats are:

Windows 7 Professional
AMD Athlon 64 X2 3800+
NVIDIA GeForce 6800 XT
2 - 17" CRT Screens
300 GB Hard drive
4 GB of Ram

and a bunch of other stuff but you get the idea. I want to upgrade the video card to something affordable but better than the one I got presently because I just need something with more kick. I am not really into playing extremely graphically intensive games except Flyff, Age of the Empires 3, and Sim City 4. But I do work a great deal in graphic programs like Photoshop, Dreamweaver, Indesign, and Illustrator (ALL THE TIME). I also do things like Bryce 3D every once in a while. Basically im looking for something good. Need a little advice on this one. Thanks.

Go with the Nvidia 9300. Has more than enough memory and power for video editing and a media center pc

We need to know the power supply you use. Specifically the wattage, though, the model number would be useful too. Not all power supplies have enough wattage to power a good graphics card. HP's website was far from helpful...
