Choosing a Gaming Video Card for your PC

Choosing the right gaming video card for your needs can be a tough decision for many. There are so many different graphics cards out there, all with different specs and features, it’s hard to know what is best for you.Your gaming video card will be responsible for producing the dazzling 3D graphics and effects seen in the latest computer games. A better graphics card makes for a better 3D gaming experience, so gamers should choose the best video card they can afford.

AGP or PCI Express
There are two ways to connect your graphics card to your motherboard, via an AGP or PCI Express slot.

Generally, a motherboard will only support one these slot types. So you need to make sure which it is before looking for a video card.

AGP has been the norm for a long time now, but it is old technology.

PCI Express is the new kid on the block, and it’s only a matter of time until it completely takes over from AGP. The benefit of PCI Express is that it can handle a greater data throughput than an AGP slot.

PCI Express offers performance of up to 4X faster than the fastest AGP slot. It’s relatively new technology, and it isn’t being used to its full potential yet. Although, we predict that games released in the next 1-2 years will make full use of PCI Express technology.

Another advantage of PCI Express is you can connect more than one video card to your computer. This is impossible with AGP, a motherboard can only ever have one AGP slot.

If you’re simply upgrading your gaming computer with a new video card, you should check whether your motherboard supports AGP or PCI Express, and then choose a card accordingly. Don’t worry if your motherboard has an AGP slot. Even though it’s not the latest technology, AGP is going to stay around for a long time. Many of the best video cards come in AGP versions.

On the other hand, if you’re building a new system from scratch, you have the choice. We recommend choosing a gaming video card with PCI Express, and a motherboard that supports it. As we said before, the games of the future will soon harness the power of this new technology, leaving AGP in the dark. So by choosing PCI Express now, it will save you the upgrade later when AGP becomes obsolete.

Also, don’t confuse PCI Express with PCI. A long time ago you would connect your graphics card through a PCI slot on your motherboard. This is very slow compared to todays standards, and is completely outdated.

ATI or nVidia
Very much like the CPU market, there are two companies that dominate the world of gaming video cards, ATI and nVidia. They make the best video card chips in the world. ATI is responsible for the Radeon series, while nVidia is behind the GeForce line of cards.

Although ATI and nVidia make the graphics card technology you see in all the latest cards, they don’t actually sell them themselves. They license their best video card chips to companies such as GeCube, Saphire, Asus, and ABit (just to name a few) who then sell their own variants on the original technology.

Rendering Features
The speed and efficiency of the GPU isn’t the only thing that counts. The latest 3D games and software make use of advanced 3D rendering effects such as anti-aliasing, anisotropic filtering, bump-mapping, pixel shaders and much more.

If you run a game that was written with such features in mind, and your graphics card doesn’t support them, you will experience a significant performance loss, or at worst the game won’t run at all. The best gaming video cards on the market try to keep up with all the latest 3D rendering techniques in the software world.

Other Functions
Video cards provide other functions apart from rendering 3D graphics. For example, you can have high-definition output, output to a TV screen, or to multiple monitors. If you want such features, be sure to check if they’re listed on the box.

* DVI: This is a higher-definition output used with newer monitors and some high-end TVs. Connecting to your monitor via DVI offers better image quality than the standard VGA connection. If you want to take advantage of DVI, buy a graphics card and monitor that supports it.

* TV-Out: If you wish to display the output of your video card onto a TV screen, you will need a graphics card that supports TV-Out. Many of the best video cards on the market have this feature, aswell as budget-line cards. You connect your graphics card to a TV using an S-video connection. If you have an older TV with an RCA input instead of S-video, you will need an S-video to RCA adaptor.

* Dual Monitor Support: If you want to split your video output across two monitors, you will need dual monitor support on your graphics card. This feature is useful for developers, engineers, designers, and multi-taskers who wish to view many different windows on their desktop at once. Usually, one output will be VGA and the other DVI.

Automation - Update Naukri Profile Using Selenium

Recently one of my friend came to me with a problem. He is looking out for new job but he feels quite boring to update  his profile on daily basis. As some people says updating profile in the morning gives you more calls as it keeps the newly updated profile on top (Although i don’t know whether naukri works this way or not 😀 ). As i was more interested to solve his problem.  After listening his problem i came to solution that instead of updating it manually lets make this job automatic. And it is quite interesting how we can automate our daily boring task with automation. Another day i came with the solution . And the solution was to make it automatic using selenium (Those who are not aware about selenium do check this link) In short, Selenium is a Testing automation Framework. And it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well....

OpenCV - Drawing a Circle with python

In this tutorial, I will show you how to draw a circle in OpenCV. OpenCV comes with lots of built-in functions that make our life easier especially when we are working on image processing .  And there is a function called circle in OpenCV which is used to draw a circle. This function takes following parameters: 1. Image : Takes an image object 2. Center : Center point coordinates 3. Radius : Radius of the circle 4. Color : Takes color in BGR format 5. Thickness : By default set to 1 (optional) 6. Line Type : By default set to 8-connected.It can also be  LINE_AA  or  4-connected  (Optional) 7. Shift:  Shifts fractional bits in the point coordinates of center and radius (Optional) Especially when we are creating closed shapes. Thickness plays an important role. Here if the negative thickness is passed in this function or any other function which creates a closed shape(rectangle, polygon, etc). Then it creates a filled shape (filled with color). Negative Thickness Filled Circle Positive ...
