Yes - I suddenly remembered inverters and picked up a little one today.
Now - the rest of the answer is one of those 'thanks, but what does
the explanation mean' scenarios. I was tempted to ask if it didn't
matter if I didn't watch any videos on it. What is covered by
'graphics tasks'? In my experience it's games players who get picky
about fast graphics cards. N I don't play games, watch TV, edit
movies or similar tasks. I don't need it to scream - would it run
much slower and would bumping the RAM up a bit make it acceptable?
