Hi, So...here I am, I am taking the plunge, the purchased has been approved and I am going to be a Max , I am going to buy a refurb, because I have always had great experiences with Dell refurbs. So I am torn between these 2 models and I need some input from users: 27" i7 2.8 with 4G ram, 1T HD and 512mg Vid 27" i5 2.8 with 4G ram, 1T HD and 1G vid Both of these models are 1699 27" i7 2.93 with 4G ram, 1T HD and 1G vid for 1899 Is the later worth the extra 200 bucks? I don't edit videos, but I might, I am simply looking for a machine that will last awhile and will do everything I ask it to for that length of time. Any personal experiences? Really just looking for someone to tell me to spend the extra 200 bucks Thank you in advance!
