I would like to add a graphics card to it. I realize this is not a gaming machine but my kids like to play star wars the old republic, minecraft, and cube world on it. So looking to make that a little easier. Any suggestions would be greatly appreciated. Thanks
7750 is OK and will most probably work with the current PSU (but barely). And some problems are possible on heavy load.
Do not search for low profile, there is space in the case, bigger cards have better cooling and lower noise.
I can recommend Asus as a brand. http://www.amazon.com/ASUS-HD7750-1GD5-V2-Radeon-GDDR5-...
The memory MUST be GDDR5, DDR3 versions are slower.
My issue was that when I installed it the computer would start and the card fan would run but no picture. I when I would take the card out my computer would run fine. I was able to get it to work by turning off secure boot and changing to legacy mode. Is it ok to leave it like that to run all the time?
