so ive been saving my pennies these past few weeks with plans on purchasing an Asus ATI Radeon HD 4850. I just went on newegg to check on it today, and noticed that the card i was going to get is only available as an "open box". what exactly does that mean? refurbished? returned item? i also noticed on the "mid range buying guide" on techspot that they changed it from the 4850 to the 4870. The 4850 was 180 before but now the open box product is like 135. Should i get that, or should i dish out the extra cash ($244) for the 4870. My pc wont be specifically for gaming since i game mostly on my 360, but i still want to be able to play some of the latest titles on my computer. any recommendations?
