I am wanting to upgrade my video card and don't know which one to choose. We are going to buy from ebay so the price isn't that important. I do love to play lots of Sims 2 games though. I have been looking at other posts and have most of the information I need. I am not sure how to find the rest of it. I have had some trouble with finding my power supply. I looked all over the back of my computer but I couldn't find it. I did find something that said 1.8v. My processor is Intel Celeron 356 and my core speed is 3333.3 mHz. The mainboard manufacturer is Intel Corporation and the model is d945gcl. The memory type is ddr2, the channel is single, and the size is 512mbytes. I am upgrading my memory to 2gb ddr2 dual channel ram which is the maximum for my computer before I get the video card though. Also, I am from KY, USA. I will keep trying to figure out the power supply. Thanks ahead of time.
