Im trying to build a good system for working in Realflow and Maya.
For Realflow its recomended to have 16 GBs of ram.

Firstly I am searching for a good motherboard and 8 GBs of ram.
I have a older core 2 duo cpu from before, Im planing to use that until i have the money to buy a core 2 quad cpu.

The motherboards Im looking into are, sorted from cheapest to most expensive:

MSI P43 Neo-F
Gigabyte GA-EP43-S3L
MSI P45 Neo-F
Gigabyte GA-EP43-DS3L
ASRock P43R1600Twins
ASRock P45TurboTwins2000
ASRock P45XE-R

I would be great if someone could give me a picture how
how easy/hard it is to get OSX to run on the above motherboards.

Best regards.

Try this:

Gigabyte GA-EP43-S3L
MSI P45 Neo-F
Gigabyte GA-EP43-DS3L

this work too, kinda expensive

ASUS P5B DELUXE
Intel DX48BT2 Extreme
Intel D5400XS Extreme

Merry Christmas

Merry x-mas and a happy new year.
