Im currently using the install to HD feature, only have a 20GB drive which doesnt really bother me. What might bother some is that now ive got GTA on there ive only got 5.7GB free, which judging from earlier on in the thread isnt going to be enough for another game. On the plus side, its abit quiter which is nice however im getting lots of bits of scenery that take ages to load. I had expected to have pop-ups go down playing from HD not get worse.
