I sold my old Xbox 360 Arcade with a 60GB HDD, and got myself a brand new 360 s with 250GB. I've noticed some weird graphical glitches in several games, like these white dot outlines in Battlefield 3:
I've never noticed something like that with my old 360. I only got myself a new 360 cos I need more HDD space, and I'm beginning to regret that decision as I had no problems whatsoever with the old one. :( Do I need to send it in for a repair, or can I just get a new one at the retailer?
