said it before, say it again...
step up blows....jsut get the card you want now, and when its time for a new one, sell old one on ebay: keep it till you get the one you ordered after your old one sold on ebay: install new card: send old card to whoever bought it on ebay.
this way, you are not without a video card. and, you're not paying 30% more for a card because you are buying it from evga instead of newegg (i know you cant get newegg in austrailia, right? but you get my point).
step up = no bueno.
