Hi to all, its a long time since i was last here and using my mac pro hex core. It was new out at the time and the last osx i used was mountain lion. then i switched back to pc for gaming purposes. and have been quite happy with the performance of a 4.6gz hex core sandy bridge and sli GFX with native sata 3. Then the other day i was thinking how much i enjoyed OSX but didnt fancy the over expensive mac pro,s on offer now. so looked at the imac instead. it has improved alot in real speed and the 3.5gz i7 haswell 27" with SSD and 780M gfx looked a good spec. the last imac i owned was a G4 1.25gz lamp shade model which was cool. but not any good in real terms today. so i just purchased my first 27" imac specs below 27" i7 3.5gz 16 gig ram GTX 780m 500g SSD I know there is a new imac with 4k or 5k screen around the corner but thats next year and it will need some decent gfx power to get the most out of that screen. so i figured that i should buy now and upgrade in 3 years and enjoy the current model. so first question to all is trim still working in mavericks? or does mavericks support trim in the OS itself?
