I tried tagging this on to a similar post to save repeat threads, but unfortunately got no response... so here it is again. I have a couple of big projects coming up this year, and I am going to need a machine to edit with. Im using logic and several plug-ins. Occasionally deals with RAW video footage, but not to edt, just to view. So here's my question... (like i said its pretty techy) Realistically I cant wait until Q1 2012 for the new sandy bridge processors, plus my budget only really stretches to the base model mac pro. (Now before everyone jumps down my throat, I am aware that it works out more cost effective to go for the duel processor models, and really i should be looking at the hex. but thats where my budget sits) Now I'll be dropping an SSD in as the boot drive, as that seems essential at the moment. but obviously the base model only has 4 dimm slots, and only 3GB of RAM. So I've been looking at going second hand, 2008/9 8core, 16GB RAM similar prices to new base model. I dont need anyone to list the hardware differences, because I know them, but what i could do with is, is someone with real world experience or using Logic with mac pros, and knowing the difference between 667MHz DDR2 and 1066MHz DDR3. That said, I understand the data transfer rates between the two, and the CAS timings, and fact that one is 2 and the other 3 channel. What I really need to know, is how this will effect my plugins, and also the performance of logic. ie, should i stick to the new mac and upgrade that (eventually). or go for a second hand one with slower but more RAM. I look forward to your replies.
