A few things that Tom's didn't mention, although it's an excellent and unbiased (and even very kind to Nvidia) review based on real-world usage:
1. These are the creme-de-la-creme cards that are in reviewers' hands, each especially hand-selected and pre-tested by Nvidia. What will be on the shelves, whenever, will be less performing at worst, or a lottery at best as to what you get.
2. Nvidia can't overclock these chips, so neither will users be able to. In fact, they had to disable shaders, etc, just to get enough to test and ready for sale, and to keep thermals and power draw down. That's why there is no 512 shader model ... it would be welcome at a Texas BBQ fest, if it worked at all for more than 5 minutes.
3. ATI 5xxx series boards have huge potential for overclocking, as users have found out. These were stock ATI boards that Tom's tested. Even ATI board partners are introducing considerably-overclocked models, and with 2 gig of memory (the Radeons are really constrained by their "measley" 1 gig of DDR5). Overclocked, the ATI cards equal or demolish the Fermis.
4. With Fermis being so close to their voltage and thermal limits already, expect to see much higher than normal failure rates once the cards are in users hands. More worrisome, if widespread rumours are to believed, this paper launch may only have 6,000 - 8,000 chips available worldwide, so getting a replacement may be difficult (or a heck of a long wait) if your Fermi crisps up, as it may well do.
No, Fermi = MAJOR FAIL. Nothing here, nothing to see, move along. And I will now start searching to order a pair of 5870's for my gaming rig. Thanks, Nvidia, I wasted 6 months waiting for these dogs to appear????
