Ok, based on the suggestions so far.. I've put together a NewEgg wishlist. While I may not order everything from NewEgg, it serves as a good place to get everything together for fine tuning.

As it stands, it's over budget. I think we can get it lower (without compromising build quality, of course). The PSU's suggested are pretty pricey. Perhaps we can start there?

EDIT: There are a ton of reviews on this card saying that it's artifacting. Is this something to be concerned about regarding mining?

Thanks
