Hey everyone, So my current situation is that I'm selling my 2010 15'' 2.66 i7 for $1500. (Good deal?). My plan is to buy a new 15'' in it's place but I'm stuck deciding whether the 0.2ghz makes up for the ~$300 difference that I'll have to pay for it after student discounts. I'm a civil engineering major starting to use AutoCAD more and more frequently. I also do minor photoshop on the side whenever I have time to touch up some photos. I plan on purchasing an ssd in the near future and I've already ordered an 8gb ram set from crucial. Can anyone justify if that 0.2ghz would make a big difference in my daily routine?
