What about dmidecode?  Run dmidecode as root, then look through the 
output for "Memory Device".  If I do that, I get 2 4096M DIMMS that are 
DDR3 and "1866 CL10 Series", but that might not be quite enough info.  
(Desktop DIMMs that are DDRx should all have the same pinout, shouldn't 
they?)  It'll tell you what exactly your CPU is too if you need that.

Make sure that the GPU is actually being used.  This is an older card, 
but it should render things faster than that.  "lsmod | grep radeon" 
should show that radeon's been loaded.  Look through the output of 
glxinfo.  There should be a "direct rendering: yes" and "Accelerated: 
yes" and probably an "OpenGL renderer string: AMD OLAND (DRM 2.50.0, 
4.17.4, LLVM 6.0.1)" ... well, not that exactly, but there should be a 
DRM and probably an LLVM in that item.  I had to do some tweaking to get 
the GPU happy with Steam on Gentoo.  I hope they've made this less 
necessary on Ubuntu, but I am fairly pessimistic about these things.
