Before making a choice should be clear what you need, a clear picture, low price, or more the number of sheets? And accordingly choose a most suitable for your camera. Specifically, should note the following:
1, the median and resolution color camera. This is the main factor affecting the price of the camera. The higher the resolution, color bits and the higher price. Present in the image color, the Olympus C-1000L and C-1400L less color cast that the picture is impressive. Fuji DS-310, the Kodak DC120 and DC210, Agfa series, also doing well. In the resolution, the better the low-resolution camera with Kodak DDC20, DDC25, Casio QV-10A and so on. If you want to buy a cheap digital camera, just shooting ID photos or the photos displayed on the computer screen, this resolution is enough. If you work in the Vehicle Administration, would like to take photographs of vehicles to be seized; or for archiving, real estate, insurance and so on, should select at least medium-resolution camera. The price is 4000 yuan. If you are for the individual photographer and newspaper publishing and printing, high image quality requirements, you can choose the Kodak DC120 and DC210 cameras, etc., the price at 7,000 yuan to more than 10,000 yuan.
2, the number of shots. On the built-in storage, the Casio QV-100 and QV-300 up to shoot 192, Olympus also offers high-end series of at least 120 of memory. If the body has PCMCLA slot machine, you can insert the appropriate memory card, thus increasing the number of shots, but the prices are increasing.
3, energy efficiency. Digital cameras usually have a color LCD device, you can always preview, view or delete any image, in the shooting to help you adjust shooting and shooting time, but it is also very power. The light-type LCD application, you can capture external light source, so that the digital camera LCD light display image, greatly increasing the battery life, according to industry speculation, after the basic digital camera will tend to lighting ceremony, is digital cameras using this technology have SANTOZ400.
4, storage media. Storage capacity of digital cameras the size of the decision you can take the number of sheets in the economic conditions permitting of course, the bigger the better card, but also need to match. Current market, there are two memory card specification, one is CF card, one is SM card, CF card is not used in the floppy disk adapter, SM card is a thin card, can be accompanied by a floppy disk in the floppy drive adapter used directly, and the price cheaper. While choosing a digital camera, traditional camera should also have professional, and should match the corresponding printer.

i5 + GT330 Samsung R780 evaluation
Like all games of this, the evaluation of the Samsung R780 also has a good hardware configuration. 2.40GHz frequency of the new Core i5-520 processor, with 1GB of video memory on the graphics card GT330M independence for the whole performance has laid a solid foundation; 4GB memory capacity of the system to be more rapid than in the past, large-capacity 500GB hard disk is more for more audio and video files stored with impunity, even if the notebook is often Xiaobian also play their game performance was filled with hope. Let us witness together the following Samsung R780 ultra-cool game this test it!
The new mid-level graphics performance to provide powerful momentum for the game
Samsung R780 main configuration list

NVIDIA Geforce 300M series laptop graphics cards already in the official announcement a long time, on the whole the new graphics card release that is previous generation GeForce 200M Series Dress to keep up with the same generation of products using 40nm process technology design, with 305M, 310M, GT325M, GT330M, GT335M, GTS350M and GTS360M seven models, games and video cards are tested in the GT330M performance level.
GT330M graphics 3DMark06 test, left 1024, the right is 1600
The order form from the official view, NVIDIA GeForce GT330M level of performance is flattening, as is GT325M can high-frequency version, the simple point that is used to 忽悠 users. NVIDIA GeForce GT330M has 48 stream processors, floating point performance 182GFlops, Shader unit frequency of 1210MHz, Memory Interface 128-bit, when equipped with the highest frequency of GDDR3 800MHz, DDR3 highest at 1066MHz, but does not support SLI. From the bottom of the card game ladder provided, you can rely on the performance of the above 3DMark06 total score, can be found GT330M playable game level graphics.
NVIDIA to seven cards from the new location, which is used to replace the previous generation G210M is the 305M, 310M, are mainstream graphics card with 16 stream processors. Replace GTS250M and GTS260M is GTS350M and GTS360M, positioning high performance level has 96 stream processors. The evaluation of GT330M and GT325M, GT335M performance level is used to replace the familiar GT230/GT240M card. Mainstream graphics cards from the bottom of the test data comparison of the performance can you see GT330M.
As independence was to join the new test in the test machine added to the user as a reference. Graphics on the PCMark05 and Vantage scores is not conclusive, and accessories will be interaction between performance, so its performance is compared to the case, only the sub-test from the graphics comparison. Test scores from the point of view, with the GT330M the 3D scores are performed well, both by a wide margin ahead of the corresponding old model.
