Just in case you're wondering, this topic is different from the other one I had posted. It's a different computer.
I want to upgrade the graphics card so that the computer will be able to handle games like Starcraft II, Runes of Magic, and Black Ops at medium settings without lagging. The power supply is 300watts. I probably need a new power supply to go with the new card. Can anyone give me a suggestion on what card I should get? It doesn't have to be a super a card that could run Battle Field 3 at high settings. I just want the mentioned games to play smoothly at medium settings, if possible. Please select the 'cheapest' card that you could think of.
Thank you for you help.
