Can you recommend a video card for me?

I want a video card that can run the majority of today's games, and is obviously compatible with my PC.

Here are my specs:

Windows 7 64-Bit.

6 Gigabytes of RAM

AMD Athlon(tm) II X2 235e Processor

250 Watts of power





I have:

One PCI Express 2.0 ×16 slot

Two PCI Express 2.0 ×1 slots

One PCI slot



My current Video Card is an Nvidia GeForce 6150SE.



The budget is $100.|||6150SE is on-board video, not a video card.



Your power supply will not safely power a video card, you need at least a high quality 400 watt power power supply to safely run a decent video card.



The following video cards will run most modern games:

GTS 450

GTS 250

9800 GT



I would not recommend ATI cards for a novice as the drivers are a headache.
