My computer has the following specs: http://ph.priceprice.com/Acer-Aspire-X1800-1070/specs/ Diablo 3 is running slow for me as I know it is for many others. From these specs, would you say that my biggest issue would be the graphics card? I am kind of a noob when it comes to computers. Thanks for your help!
You don't have a lot of options due to the case being a slim-case, so at best, is Radeon HD 6570 Low-Profile Ready
I recommend outright getting a new computer. The CPU and GPU are both extremely outdated. You'll need a low-profile video card, and even then, you'll be hoping that your CPU doesn't bottleneck anything.
