The new Mac mini models provide a great leap in processor performance over the previous generation.... Graphics test results were a bit surprising, however. The 2.3GHz Core i5 Mac mini, with its integrated Intel HD Graphics 3000, wasn’t as fast as the older 2.4GHz Core 2 Duo Mac mini and its integrated GeForce 320M graphics. The older mini was able to display 42 percent more frames per second in Call of Duty and 7.5 percent more frames per second in Cinebench OpenGL test. The 2.5GHz Core i5 Mac mini, with its discrete AMD Radeon HD 6630 graphics, showed a vast improvement; compared to the old 2.4GHz Core 2 Duo Mac mini, it was able to display nearly twice as many frames per second in Cinebench’s OpenGL test, and 53 percent more frames per second in our Call of Duty tests.
Among many other applications, the Mac Mini has been extremely popular for use as a music server, in high quality audio systems.

Overclocking takes an already strong integrated graphics platform and makes it even better. The gains are very real and palpable.... It clocked farther and gained more benchmark and gaming performance than expected, which is always a good thing.
And some user comments on this AMD Fusion Accelerated Processing Unit (APU), combining a quad-core CPU and integrated GPU (click the "feedback" tab):

Intel is now offering dual-core Sandy Bridge processors under Pentium brand. They lower the price for the “LGA1155 Club” membership quite noticeably, because they are selling for less than $100 a piece. Does it mean that the new Pentium processors may become a new perfect combination of performance and price? Let’s find out!

Physicists at the University of Arizona have achieved a breakthrough toward the development of a new breed of computing devices that can process data using less power...
"Spintronics has the potential to overcome several shortcomings of conventional, charge-based computing"...
Current microprocessors digitize information into bits, or "zeroes" and "ones," determined by the absence or presence of electric charges.... In spintronics, only the orientation of an electron's magnetic spin determines whether it counts as a zero or a one...
Amazing stuff happening!
Spintronics could be a stepping stone for quantum computing, in which an electron not only encodes zero or one, but many intermediate states simultaneously
Say what?? wow! Seriously.

The Obama administration is leading a global effort to deploy "shadow" internet and mobile phone systems that dissidents can use to undermine repressive governments ...
The U.S. effort, revealed in dozens of interviews, planning documents and classified diplomatic cables obtained by The New York Times, ranges in scale, cost and sophistication...
It has brought together an improbable alliance of diplomats and military engineers, young programmers and dissidents from at least a dozen countries...
Wow, and I remember when the Internet was just for fun...

Seeing a bunch of scores for 240GB+ drives is frustrating to all involved. At these capacities you're almost always looking at two die per NAND device, which has significant performance benefits due to interleaving. Not only are 240GB+ drives the best case performance you'd see from a particular SSD, they are also very expensive. At around $2/GB you're looking at over $500 for a high end 240GB+ SSD. I've spent the past few weeks gathering modern SSDs with 128GB of NAND on-board to provide a look at a more balanced point in the price/capacity spectrum.

Even though Advanced Micro Devices' next-generation FX-series microprocessors code-named Zambezi and powered by Bulldozer micro-architecture are projected to bring the company back onto the market of high-performance desktop microprocessors, the new chips will be relatively affordable. For example, the highest-performing model will cost $320, according to a media report.

Intel Corp. said on Wednesday (May 4, 2011) that its 22nm technology will employ triple-gate (Tri-Gate) transistors. The three-dimensional Tri-Gate transistors represent a fundamental departure from the two-dimensional planar transistor structure that has powered all chips for decades. Other makers of chips, including Intel's arch-rival AMD/Globalfoundries will also eventually start to use 3D transistors.
"Intel's scientists and engineers have once again reinvented the transistor, this time utilizing the third dimension. Amazing, world-shaping devices will be created from this capability as we advance Moore's Law into new realms," said Paul Otellini, chief executive officer of Intel.

First and foremost, why on earth would someone put water in their computer?! Well, there are several very good reasons. It can result in better temperatures, higher overclocks, a quieter running system and it can just plain look good.
Whatever your motivation, water cooling can accomplish all of those and then some. Before you jump into this facet of our hobby, itís always best to plan your water loop from start to finish; from the ground up ....
