5th replacement in 5 weeks?!! That's definitely not right. Unless you're doing something you shouldn't be, I really don't think the dvd-rom is the problem. It' s far more likely the software or something else.
Yeah but specificly for the i9100 off the Dell website? I would feel a lot better with a graphics card that was actually meant for i9100 and not ixps. Granted it propably doesn't matter a whole lot but I don't need it immediately either.
