Power consumption might not mean much at first glance. For HTPC, its very important, but well, i dont really care about HTPC, and this thread has nothing to do with HTPC. Anyway, power consumption actually can be important. 750 watts is generally ideal for people who consider dual cards setups, but only want a single card currently. With Fermi like psu consumption, it generally takes a 850 watt. Also, the added power of say a 480 over a 5870 can cost quite a decent bit per year. $20-50 per year based on quite a few variables. So while i dont think its as important as price, heat, raw power, features, and so on, but it definitely isnt something that should be brushed off.
