The only problem with waiting is that even though you may have the 'latest tech' - there will be bugger all that supports it for quite a while. By the time it's widely adopted, there are usually several revisions to that tech which bring a whole range of improvements. Sometimes early adoption can be more trouble than it's worth. SSD's are a prime example. The 2nd-3rd gen drives are much improved over the originals. If you can wait until after xmas, the prices and availability of the 58xx cards should have improve significantly.
