Hi. I have a Dell 4300S with a 180W power supply and an ATI Rage Ultra video card. I loved Half Life, and would like to get Half Life 2. I understand, though that my video card is inadequate. Is there any way to buy just a video card, and not a power supply too? Seems like many new video cards require bigger power supplies. Is there one that will run Half Life 2 passibly, but will run with a 180W power supply? If I do have to replace the power supply, is this something I can do myself, I do I have to take it to a shop? Put differently, what's the least amount of $ I can spend and still be able to play the game? I am an extreme tightwad.
