I have a strange questions for those of you that have mac pros. I have a new imac (w 4 gig ram and snow leopard) and while the performances are ok I still see a lot of lag in the os and a lot of beachballs. Especially in vmware, the finder, spaces and expose and the browsers. Once im ina program (like words) everything works fine. the multi tasking seem to be the issue here but I'm unsure. Now I need a windows xp or 7 machine for day trading via vmware and latency is real important and I'd really hate to leave the mac behind. ideally I'd have a win xp side with trading stuff on one space and the rest on the mac side. spaces is awesome I'm a heavy multitaskers and I run these programs all day: mail coda netnewswire firefox (3 windows about 30 tabs) safari (2 windows 10 tabs) adium address book terminal itunes vmware with trading stuff transmission words text edit mamp My Q: will a mac pro and a couple of raid0 ssd be essentially beach ball and lag free or is the problem within the software itself (os and 3rd party)? I ask as I often upgraded in the past (both macs and PCs) thinking adding hardware would help a situation and it did but never quite enough. Basically, will throwing hardware at the problem help enough to make a difference or will it just burn a hole in my pocket? I know for a fact it will help but up to what point? Will all these extra cores be used for multitasking or will they just sit there and idle like in vista? Will there still be lag and beachballs just less so?
