No, I do not think your midas version will be affected by upgrading
the pc or display memory, all the contrary it may works even 
faster. The only thing you should take into account is to maintain
the same bitdepth configuration for your Xserver (8 or 32bit).


Here I do post again previous emails regardings this problem:
