Problem: Article: Graphics cards can easily become the most expensive component in your computer, but they don't have to be. Many of the budget and midrange cards can still provide great performance, depending on your needs. If you are a gaming enthusiast that has to play the newest games at the highest possible settings, you'll want to look for the more powerful and expensive cards. If you only game occasionally, aren't worried about the newest releases, or don't mind sacrificing a few graphics settings, you can get much more bang for your buck by looking at midrange cards. If you just want to watch HD video or play a few 2D games, most budget cards should do the trick.  Do your research before putting your money down. Sites like Tom's Hardware (tomshardware.com) and PCWorld (pcworld.com) regularly test and provide comparisons for many of the most popular new and upcoming graphics cards. These test results can help you quickly see how all of the available options stack up against each other. Don't worry about the amount of memory (RAM) the graphics card has. Inflated amounts of memory are often used to make poor cards look more appealing. What is important, however, is the memory bandwidth. This is the speed that the memory can send and receive data from the computer. GDDR5 is the current leader in this category, and will significantly outperform four times the amount of the older GDDR3 memory.  If you have a midrange CPU, you're likely not going to get the most out of a high-end graphics card. The graphics card is an important factor for performance, but games rely on all of the components in your computer in differing capacities, including the CPU, the system RAM, and even the hard drive read and write speed. 4K gaming is becoming more and more of a reality, but it will require a top-of-the-line graphics card (or two) in order to get satisfactory performance out of your games at that resolution. Keep this in mind if you're in the market for a 4K monitor as well. Before purchasing your new graphics card, you'll want to check a few things inside your case or in your computer's documentation. Remove the side panel from your computer by loosening the thumbscrews or regular Phillips screws along the back. Typically, you'll be removing the panel opposite of the motherboard's Input/Output panel on the back of the computer.  Except in very rare circumstances, it is not possible to upgrade the graphics card on a laptop. Refer to your laptop's documentation to determine how to upgrade its graphics card if possible. When opening your case and working inside your computer, make sure that you are properly grounded. This will help prevent electrostatic discharge that can damage your computer components. You can ground yourself by using an electrostatic wriststrap, or by touching a running water tap before working in the computer. Graphics cards are one of the biggest draws on your power supply, so you'll want to ensure that your power supply can handle the power requirements of the new card. Different cards draw different amounts of power, so check the specs on the card you want to buy, as well as the specs on your computer's power supply.  There are a variety of power supply calculators online that you can use to enter in all of your components and see the minimum recommended wattage. You'll want a little more than the minimum to future-proof your computer. Another general rule you can follow is that you typically will want a power supply that supplies double the wattage that your graphics card requires. If you're installing multiple graphics cards into a single computer, you'll likely need a power supply that provides at least a kilowatt of power. There is no way to determine a power supply's wattage without physically looking at it. There is no software that can report the wattage. Nearly all power supplies have a sticker that is clearly visible on the side which will tell your the power supply's specifications. You can usually just remove the side panel from your computer and visually inspect the sticker. Many of the more powerful graphics cards require one or two 6-pin connectors (PCIe) from the power supply. Most newer power supplies should have these cables, but older power supplies will not. You can get adapters to connect to one of the other cables, but you may be better off replacing the power supply anyway if it's that old. Graphics cards have gotten quite large, and if you have a small case with tight spaces, it may be difficult or even impossible to insert the card you want. Use a tape measure to measure the space where your graphics card will be inserted. Check this space against the specifications of the graphics cards you are looking at. Make sure to pay attention to the width as well, as many of the more powerful cards can be quite wide. A graphics card may take up the width of two PCIe bays, but it will only need to plug into one slot. Nearly all modern graphics cards run on the PCIe interface, which replaced the outdated AGP method. If your computer was purchased or built in the last ten years or so, chances are that it uses PCIe. If you're trying to upgrade the graphics card on a really old computer, you may be stuck with AGP unless you upgrade the motherboard as well.  PCIe and AGP slots are colored differently on the motherboard. AGP is typically a darker color such as brown, while PCIe is usually white, yellow, or blue. There is no standard, however, so refer to your motherboard's documentation or look for labels next to the slots. PCIe slots are typically located closest to the CPU on the motherboard.
Summary: Balance budget against power. Open your computer case. Examine your power supply. Measure the space where the graphics card will go. Check your motherboard's compatibility.

In one sentence, describe what the following article is about: In order to properly credit an image, you need to gather as much information as you can. Once you’ve located the original source for an image, try to find the name of the person who created it.  This could be the name of the person who runs the website where the image is hosted. This could be a username (especially if the image originated on tumblr, pinterest, or other social media sites). Look for a caption, scroll over the image to see if additional information comes up, or attempt to save the image to see what the file is named. If possible, try to determine when the image was created. If the image in question is a representation of an existing artwork or photograph, include the date that the original work was created.  If you are working with a web-only image, see if the website hosting the image has information about image usage or copyright. You may be able to find the date of creation there. If you are citing an existing artwork, an internet search should be able to tell you the date of creation. If you are citing an artwork, you’ll also need to mention where the original piece is held. List the name of the gallery, library, or museum. Also, list the city where that institution is located. For instance, if you’re talking about Dali’s The Persistence of Memory, a quick internet search will tell you that it is held at the Museum of Modern Art in New York. Write down the name of the website and/or database where you located the original image. If the website is run by an organization, sponsor, or publisher (such as as a university press), you’ll need to record that info as well. Materials online are changing all the time. As such, it is important to note the date of access for an image (the date when you saw and/or downloaded it). Including this is not always required, but it helps add credibility to your citation.
Summary:
Determine the image creator's name. Find out the title of the image. Determine the date the image was created. Figure out where the original is located. Record the place where you accessed the image. Record the date when you accessed the image.
