Buying new computer, worth upgrading mobo?

[eksaint]

So I'm buying a new computer with a Amd Phenom Ii X6 1075t 3.0ghz Processor.

I can select to upgrade the motherboard but am not sure if it's really worth it or if I will see any real differences.
One thing I want is dual monitors I'm upgrading the graphics card to have two dvi outs, if I went with a Ecs A785gm-M Am3 Esata2 Hdmi Dvi & 1394a would this give me the ability to have dual monitors using the onboard video?

Below is the list of my options, give me your thoughts, thanks very much in advance.

1394A is for Firewire 400 connectors, and absolutely nothing to do with your video card.

Considering the new AMD "Bull Dozer" platform is due to be released shortly I wouldn't go mad on a new motherboard.

Most of todays current graphics cards will come with the connectors to facilitate the connection of at least two displays, so that shouldn't be an issue.

You'd just use the two outputs on the graphics card.

Conventionally, having a graphics card means disabling the onboard graphics but they are sort of changing that now (see nvidia optimus for laptops). Also I'm not sure if you can use two outputs of onboard graphics simultaneously. But as mentioned before, two outputs of a separate graphics card are fine.
