Okay, SO... I have my 2.16ghz Core2Duo macbook Pro with the X1600 128mb Graphics card... I've been thinking that I should sell my macbook Pro and get a newer macbook pro, either a 2.2 or 2.4ghz with the 256mb nvidia card... OR...... My macbook pro is now out of warranty coverage and I had a thought... Maybe for about $300-450 i could get a Macbook pro 2.2/2.4ghz logic board and replace the one in my current machine and then sell my old logic board on ebay for around $200-300 .... I'm super experienced with working on small computer hardware, i've fixed quite a bit of macbooks with broken LCD's now. What do you guys think?
