I was trying to install a Geforce GT 730 GPU to a recently purchased Aspire tc-895-ua91. However, it seems to be not compatible. I can hear a beep warning when power on the desktop and it does not have any output. I am wondering if anyone has ever successfully upgrade a GPU for tc-895-ua91. I called the Acer custom support and they even don't know what GPU is compatible for this desktop. Many thanks, everyone.
