I'm getting purple fuzzy's around the shadows in-game in GTA4, and my box has RROD'd twice in the past week. It bounces back immediately on reboot as of right now, but it looks as if this one's on a downward spiral.
Looks like within a few weeks I'll be swapping it out. Does anyone have any experience with swapping one out at Best Buy on their warranty program and them allowing you to upgrade to the Elite? I want to keep all the info on my HD, so I guess I better start saving critical game saves over to a memory card.
