Hi I have a mid 2011 mac mini 2,3 i5 and 8 Gb ram. Runs on Mountain Lion. I use it as a host for my external harddrives were I have all my music and movies, they are Firewire 800. I use screen sharing and using my MacBook Pro Early 2011 as screen. They are connected with WIFI using airport Extreme. It has working very well, but the mini has beeing slow, not only with iTunes but also with browsing. After uppgrading to Mountain Lion the machine is like syrup, browsing take forever and iTunes is soooo slow. Was slow befor uppgrading but now it is useless. My biggest problem is my iTunes library. It is huge. 1 TB with music and with movies it is total 1.4 TB. So my question is should I upgrad to the new mac mini, and do i need the Quad core i7? Will it improve iTunes performens with SSD disk? I know that this huge iTunes library will be a bit slow, but what is my best option?
