I got a great computer but I need more RAM. Currently I have 8 gig. Is there a way to tell the type of RAM I need w/o cracking the case? Hmmmmmm..... I think it may be I need a new GPU. I got a 360 image open in GIMP and I am trying to manipulate the view with GEGL Operation panorama-projection and every time I change a value it redraws the image block -by block slowly. My current GPU is:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV770 [Radeon HD 4850]

Do I need a new one or do I need to activate it or something like that?
