my early 2009 has a 2ghz core 2 duo and the nvida 9400 I put in 4 gigs of memory and a 500 gig drive. but sometimes it can be a bit slow. But I am wondering if I would see much of an improvement with a new one without spending 900 to 1000. going that high I might as well get a imac. but even 600 is about the limit of what I should spend. then I would sell the wife and I's minis and buy her a new one too. I try to go 3 yeas or so between upgrades but I am not sure if it is worth the money yet.
