i currently have a MBP 17in 2.33 ghz. got it in 07. its been pretty good, but recently has gotten sluggish. i did a clean install of snow leopard. that helped a bit. then my fans started making those loud noises and needed to get replaced. now my let 1/3 of my screen is a bit dimmer then the other 2/3s, only noticable on lower brightness settings. I have the opportunity to get the new 13in MBP 2.26 ghz at a good price. do you think i should upgrade? will performance be the same, better worse? i used to game a lot but now mostly schoolwork and youtube. let me know what you guys think
