The trouble I have is that the tower I have is a SFF ( Acer X3810 ) so I'm told only a low profile graphics card would fit, so in theory could I just buy a new case , graphics card and and possibly a psu should it require it ? Ive read that ssd's make a hell of a lot of difference to loading times, any ideas what would best suit it ? I was led to believing would need an i7 processor to run it at high !
