Hello everyone, I have an older Gateway PC model GM5066e. Purchased an Nvidia 9800GT graphics card, and it has worked nicely for Call of Duty for the kids for 3 years. The original power supply was only 305 watts, and it was underpowered, but still ran very well. The 9800GT finally stopped working 2 days ago. yesterday. I just replaced the original PS to with a 520 watt unit last night. Now looking to replace the 9800GT. With a 5 year old PC, and an upgraded 520 watt PS, what would be a decent graphics card that should be compatible with the motherboard? Looking for something in the $100-$125 range. Thanks!
