Sandy Bridge Build

Its an everything rig - Gaming - programming - video editing - photoshopping etc.
It has to last 4 years or so.
I am more worried if the components are OK - no issues with compatabiity etc - worried about the add on cooler and RAM wheter it fits with that board.

If you go with the Asus P8Z68 Deluxe as opposed to the Pro, it comes with dual Ethernet ports built in. (As well as getting a few extra things)

If you need the dual Ethernet ports, you might as well get a motherboard that builds them in as opposed to having to buy an extra card.

1) I think the ram is ok. But check it out yourself first.
You want documented ram compatibility. If you should ever have a problem, you want supported ram.
Otherwise, you risk a finger pointing battle between the ram and motherboard support sites, claiming "not my problem".
One place to check is your motherboards web site.
Look for the ram QVL list. It lists all of the ram kits that have been tested with that particular motherboard.
Sometimes the QVL list is not updated after the motherboard is released.
For more current info, go to a ram vendor's web site and access their ram selection configurator.
Enter your motherboard, and you will get a list of compatible ram kits.
While today's motherboards are more tolerant of different ram, it makes sense to buy ram that is known to work and is supported.

2) A GTX580 needs only a 600w psu with 42a and a 6 pin and a 8 pin power connector. A 1000w psu is more than you need, even for planning on sli.
A 700w psu could handle a GTX590. If you ever wanted more graphics power, just sell the GTX580, and replace it with a GTX590. But, more likely, the next generation 28nm kepler will be out, making that a more attractive upgrade.

I am. In Australia there is a $90 difference...

as it is I am going to try to stretch the budget to the deluxe

That site is one of the better priced in Australia...
