First,I've been reading Toms so long,it's about to I showed up and I'm desperate. I'm not the richest man,my brother in law gave me an Acer tower pc ATC-705-UR53. Processer is an Intel G3250, graphics Intel HD ,1TB hard drive, 4GB DDR3 Memory. Also upgraded to windows 10 .I just want to to play a few flight games. Me and especially my Military brother in law who learned some about PCs would like to add a graphics card. I have to do the foot work. I admit,I'm over my head. I looked, but there's always something different from one Acer to another.
