I've been super impressed with how helpful and knowledgeable people are on this site. I was hoping to get some help of my own...I'm looking to upgrade my computer's integrated graphics card with something that will allow me to enjoy games like Fallout New Vegas, Mass Effect 2, and Oblivion. My budget is limited to something close to $200. My computer is running Windows 7 Professional. Here are a few specs: Processor: AMD Athlon (tm) 64 X2 Dual Core Processor 5000+ 2.60 GHz RAM: 4GB System Type: 64-bit OS I know power supply is a huge determining factor but I don't understand how to make anything of the info there. This is what it says: AC Input (47-63Hz): 100-127V/6A 200-240/4A DC Output: +5V.../25A , +12V.../14A +3.3V.../18A , -12V.../0.8A +5VSB.../2A +5V & +3.3V Shall Not Exceed 165W +5V & +12V Shall Not Exceed 218W Max. Output Power: 250 W If my power supply is too limiting for a halfway decent graphics card I'd be willing to upgrade. If you think that ought to be done, what would be an affordable and compatible option?
