Earlier this year NVIDIA announced a new technology rather cool. This is called Optimus and Nvidia graphics he finally switching, where a laptop can choose between integrated graphics (for better battery life) and a dedicated chip (for better performance), a dominant characteristic. How? By doing this automatically on the fly, and no user intervention required. We waited patiently for laptops Optimus to go on sale today, and the K52JC Asus is the first to land in our labs.

If you are interested in the nitty gritty of Optimus, it is worthwhile taking a look at our Guide Nvidia Optimus. We will focus on K52JC, however, and indeed this is not the most obvious candidate for the technology. With a screen of 15.6 inches and weighs 2.5 kg, this is not exactly portable, which makes the power savings potential of something diminishing returns. It is akin to a hybrid Bugatti Veyron.

Samsung Q-series notebooks is something of a timeless classic. Although rarely the most glamorous or sophisticated, they still have the portability and affordability balanced extremely well. Of course, there are more choices in affordable and portable laptops these days, but the Q330 continues the great tradition of his ancestors.

Unlike the likes of Asus UL30A, the Q330 uses the full power of Intel Core i3: He who has two cores running at 2.26 GHz, actually. This gives it a significant advantage in overall performance, although Intel’s Graphics HD there is no better a game machine Peeking under the hood reveals over 3GB of RAM and a 320GB hard drive, which is perfectly adequate considering the price £ 600 application.

There are two versions of the R580 on sale now and we’re reviewing the most expensive of the two, the R580-JS02UK. Both use the same Intel Core i3-330M processor, which runs at 2.13 GHz with 3 MB of L2 cache and a 512 nVidia GeForce 310M graphics card.

But while our backs this model with 4 GB of DDR3 RAM and hard drive 500GB and £ 580 asking price, cheapest JS03UK has 3 GB of RAM and a 320 GB and can be purchased for around £ 525. In most other respects, however, both are identical and that Samsung fails to install a 64-bit version of Windows 7 Home Premium, despite including 4 GB of RAM, both should also be performed. Other specifications include both Wireless-N Wi-Fi, Gigabit Ethernet and Bluetooth 2.1 + EDR, covering all the basics you want at this price.

Samsung generally prefers to stick to the mainstream segment of the notebook and R730-JA02UK we are considering today is a good example. It’s a 17.3in laptop replacement office that sells for around £ 480, making the Samsung R730 a potential option for anyone who wants a machine, major functional at a reasonable price.

Despite measuring a large 441mm diameter, the R730 weighs only 2.84 kilograms, which is light enough for such a large machine. This is mainly because the R730 is not burdened by physical too advanced, as a discrete graphics card. Consequently, there are many open air inside the machine, it is rarely hot or noisy. Of course, this also means that it is no gaming laptop, but one would not expect to be at this price. Outside of 3D applications, however, is a performer decent. Its dual-core Intel Pentium T4200 at 2.1 GHz as well as ticks and put in a good performance in our benchmarks. Provided you stick to fairly regular computing tasks, it can easily cope, which extends even to some video editing.

Despite being “Brand New”, Intel’s Pine Trail Atom platform, which does not improve too much on its predecessor in terms of functionality. So while technically new, we are always looking at netbooks each manufacturer clones that are more or less from each other.

This is particularly true of the Acer Aspire One 532H because it is literally engineering the same DNA as the S2 Packard Bell Dot, we reviewed recently. Of course this makes sense as PB is now a subsidiary of Acer, so let’s see how the two netbooks differ from each other. Given the success of Acer on this market, behind Acer Aspire One is one of the best selling models of the first generation, the 532H has a little height and in terms of looks marry. Our model, wearing a black cover with bright red spots or subtle, looks rather fetching, if it does pick up fingerprints easily. As Ruby Red, One should be available with Sapphire Blue Pearl and Silver options.

Blu-ray is far from being a ubiquitous feature on laptops, but Toshiba has finally understood that any “mobile multimedia computer” Should be standard. Acer has time he has proposed in its range and the Acer Aspire 5942G (524G64Bn), machine 15.6in desktop replacement, is his latest effort. It also packs a new laptop processors Intel Core i5 which, among other things, gives a line 940 pounds heavy price.

As always with Acer, however, the 5942G is an excellent once you tot up all the features. Notwithstanding the Intel Core processor i5-520M two hearts starting at a brisk 2.4 GHz – and the Blu-Ray, it also offers a very high capacity of 640 GB HDD, 4 GB of 1066 MHz DDR3 RAM and a decent ATI Mobility Radeon 5650 graphics card with 1GB of dedicated memory.
