AMD Radeon HD 6970 & Radeon HD 6950

AMD Radeon HD 6970 & Radeon HD 6950 - Last month, Nvidia launched its GeForce GTX 580, but we told you to hold off on buying it. A week ago, Nvidia launched GeForce GTX 570 and we again said "wait." AMD's Cayman was our impetus. Were Radeon HD 6970 and 6950 worth the wait? Read on for more!

In the world of high-end hardware, waiting for the next great thing means reading about a lot of technology and never actually buying a new piece of gear. That’s no way to enjoy your favorite games though, is it?

Sometimes the wait is worth it, though. Last week was a perfect example. Nvidia launched its GeForce GTX 570, but we already knew AMD’s Radeon HD 6970 and 6950 boards had shipped out, FedEx Next Day Air. How could we not recommend waiting to see how these boards would compare? The very same morning, AMD launched a refresh on its Phenom II and Athlon II processors, incrementing clock rate. But we have Intel’s Sandy Bridge-based CPUs up and running in the lab. Again—why wouldn’t you wait a couple of weeks to see how they stack up?

I was particularly interested in the performance of the Radeon HD 6970 and 6950, the two cards AMD had shipped so urgently. Whereas the Barts GPUs used to build Radeon HD 6870 and 6850 centered on the same VLIW5 architecture that earned Radeon HD 5870 a place in infamy, the Cayman GPU consolidates functionality into a VLIW4 design, incorporating fewer ALUs per thread processor, but improving performance per square millimeter of die space. How would that translate to the experience you get when you plug a 6900-series card into your system? Well, since Cayman is larger than Cypress, we have to assume it’s also going to be faster.

Urban Meyer Stepping Down

Urban Meyer Stepping Down - Well, it appears as if it’s deja vu all over again.

Less than 12 months after retiring and then un-retiring, Urban Meyer is apparently stepping down as Florida’s head coach. There’s no word on if he will be stepping back up tomorrow.

Urban Meyer Stepping Down

According to Todd Wright of Sporting News radio, and AOL Fanhouse‘s Brett McMurphy Meyer will announce at a 5 p.m. ET press conference Wednesday that he is resigning/retiring as the Gators’ head coach. There are no further details available at this time, other than GatorUpdates reporting over the weekend that Meyer checked into a hospital the week of the UGA game and has been undergoing tests since.

Obviously, we’ll have more on this story throughout the day and well into the night…

Matt Cassel Undergoes Appendectomy

Matt Cassel Undergoes Appendectomy - The mystery of Matt Cassel missing practice Wednesday coupled with the Kansas City Chiefs promoting quarterback Tyler Palko has been solved.

The team has announced that Cassel underwent an appendectomy on Wednesday morning. The Chiefs say they expect Cassel to return to work this week. Returning to work and being ready to perform well in the team’s biggest game of the season on Sunday against San Diego are two different things. ESPN’s Adam Schefter is reporting the Chiefs are viewing Cassel as being questionable to play in the game.

Clearly, this is terrible timing. The Chiefs are 8-4 and would take a major step toward the playoffs with a win over the Chargers. Cassel has played very well for the past two months. If he can’t play, the brittle Brodie Croyle would face the Chiefs in his first action of the season. Croyle last played in Week 13 of the 2009 season.

100-calorie Packs Diet

100-calorie Packs Diet - Did you know recent studies show chronic dieters tend to consume more calories when foods and packages are smaller? Consumer behavior was observed in the study regarding "mini-packs," 100-calorie food packages that are marketed to help people control calorie intake.

The study revealed that one group that over-consumes the mini-packs is chronic dieters - individuals making a conscious effort in trying to manage their weight and food intake.

This shows that the distorted perception of small packages may actually undermine dieters' attempts to limit calories.

Consider this: Consumers perceive the mini-packs to be a generous portion of food - numerous small food morsels in each pack and multiple mini-packs in each box - while on the other hand, consumers perceive the mini-packs to be diet food. For chronic dieters, this perceptual dilemma causes a tendency to overeat, due to their emotion-laden relationship with food.

In a series of focus group studi…
