Can my setup play Aion without my gfx card?

Ok, so some of you may be familiar with the new mmorpg Aion. Well, I recently ordered a bunch of parts from newegg to build me my own pc mainly for Aion. As a lot of you know the radeon 5850 gfx cards have been out of stock almost everywhere lately... that being said, I will most likely be getting all my parts in by tomorrow, but the gfx card is the last piece I will be missing until "a week or two" according to some other place where I have one reserved for me when they get their shipment. Would I be able to play Aion without any gfx card and would it be safe for my computer? I have no idea how that kind of stuff works, since I've never used the onboard display connection before. Oh yea, here are my specs:

I mainly want to know if its safe and wondering if anyone does that

@ Djsks...How I hate you
I doubt the onboard will play Aion but you can cause no damage by trying. The most likely thing to happen is the game will just tell you there is no compatable grahics card available.
As a possible cure for the wait, what about a pair of HD5770s? The system you have on the way will run them easily enough.
