We're pleased to announce a new addition to our selection of Product Face-offs: heatsinks.

Today's processors kick out more heat than ever before, buy an efficient heatsink allows you to keep things cool on the inside and quiet on the outside.

We've already looked at seven or eight heatsinks whose details are already in the Product Face-off, and there are full reviews of around half of these too--the rest are on their way, don't worry!

To complete our coverage of heatsinks, we've also got a complete Product Survey here where you can read all of the tests and find out what you should be looking for.

Effective 19 October, Intel will be reducing the price of some of its existing processors to make way for new models.

The Santa Clara based manufactuer will be taking around 5-15% off the lines it sells to other hardware developers--the prices shown here in US dollars are only available commercially in batches of one thousand CPUs.

Model	Former Price (per 1000)	New Price (per 1000)	Change
Intel Pentium Dual Core E2220	84 $	74 $	- 11.9 %
Intel Pentium Dual Core E2200	74 $	64 $	- 13.5 %
Intel Core 2 Duo E7400	-	133 $	-
Intel Core 2 Duo E7300	133 $	113 $	-15.0 %
Intel Core 2 Quad Q8200	224 $	193 $	-13.8 %
Intel Core 2 Quad Q6600	193 $	183 $	- 5.2 %

As you can see, the entry-level price for a quad core processor continues to fall, with the Core 2 Quad Q6600 slipping below 150 euros for the first time.  Although only marginally more expensive, the Core 2 Quad Q8200 offers improved energy efficiency but no gain in performance.

Following these adjustments, the next step will be the arrival of the Intel i7 line, which is expected to arrive next month.

Although only the Japanese press are officially in the loop for the time being, Nintendo yesterday unveiled the next version of its portable games console, the DS.

The new DSi's two screens are now bigger, and its camera will be replaced with a 3 Megapixel model capable of recording video at 640 x 480 resolution.

The Sony Bravia W5400 and Z4500 both arrived in our labs this morning, and we're looking forward to testing them out in 40'' and 46'' versions very soon.

The W4500 is an update of the earlier W4000, which scored a handsome five stars when we reviewed it back in April. Fully equipped with Motionflow 100 Hz, we'll be bringing you the test results on Monday.

As for the Z4500, it's the first TV to feature Motionflow 200Hz.  It'll find its place in our Product Survey for TVs from next week.
