    Choosing a GPU - The Core Basics

    Information There are many factors to take into consideration these days when choosing a GPU. With the myriad of hardware combinations and multiple versions of numerous cards available it’s become somewhat of a minefield as to whether the GPU you’ve chosen for your system will actually prove to be the correct choice.

    Below we’ll look at some of the major factors you should look into before purchasing a GPU as a mistake could prove to be very costly, especially when you’re in the market for a higher end GPU.

    Tip Always check the game developer or software vendor's recommended graphics requirements when buying a GPU for a specific game or piece of software.

    PART ONE [/i] Usage
    First and foremost you must take into consideration what youre going to be using the GPU for. Most instances of needing (or wanting) a new GPU will be down to gaming, and gamers will be looking to get the best GPU they can within their budget for the highest framerates and smoothest gaming experience. Gaming relies heavily on GPU power so this is pretty much a given.

    The choice between AMD and nVidia will more often than not be down to personal preference and its always a good idea to check online benchmarks if youre not certain which camp you want to go with. Its virtually always the case that AMD cards provide better bang for buck with nVidia cards weighing in with substantially higher prices, although this doesnt necessarily mean that nVidia cards automatically give better performance.

    Both companies offer their own additional perks, for instance AMD have developed Mantle while nVidia offer Geforce Experience. Again, more info to be taken into account.

    So do your research and decide which team you want side with.

    Its important here to understand the need for VRAM. In computing terms its usually the case that the higher the number, the better performance. And while this remains true in regards to VRAM, sometimes that extra performance isnt needed and money can be saved from making an educated choice.

    Lets take nVidias GTX 770 as an example; the 770 is available in two models, the 2GB VRAM model and the 4GB VRAM model. Now if youre using just one 1080p monitor the 2GB model will be more than adequate and there is no need for the extra VRAM, it wont be used and the extra 2GB (along with the extra cost) will be wasted. On the other hand, if youre running a multiple monitor setup, a higher resolution monitor or a 3D monitor then the extra VRAM will not only come in handy but will be a must.

    For non-gamers, it will always be wise to check whatever recommendations are made by the vendor of the software youre planning on using your new GPU for. In some cases you wont need a top end graphics card, and while in some photo and video editing suites GPU acceleration can be utilised it may be overkill going for a top end card when a mid-range card will be just as beneficial at a lower cost. For day to day use with no gaming, rendering or editing then lower end cards should be considered, and in some cases the onboard graphics offered by most systems will be more than adequate.

    To summarise, do your homework on what you need from your card before making a purchase. Graphics cards arent cheap and you want to get it right first time. Budget will be a big factor in determining what level of GPU you can buy and with the plethora of cards out there (whether reference or manufacturer aftermarket) its critical you get the best card available for your money.

    PART TWO [/i] Power Requirements
    The PSU (Power Supply Unit) is probably the most overlooked component of modern PC building. Time and again cases arise where someone has built (or bought) a system and cheaped out on the PSU as it only provides power. On the contrary, the PSU is one of, if not the, most important part of a build. Its always recommended to have a quality PSU with Corsair (my personal recommendation) and Seasonic being widely regarded as the best of the best.

    When looking for a GPU then you must look to your PSUs rating before making a purchase. Manufacturers will always give power recommendations on their website so this is a pretty easy piece of information to look up. Below is a guideline for the previously mentioned GTX 770, the first shot is from the nVidia website which is the recommendation for a reference 770, the second screenshot is from a retailers listing for an ASUS 770 Direct CUII manufacturers aftermarket card.

    PART THREE [/i] Size
    A lot of todays cards are absolute monsters when it comes to the sheer size of them and again this another factor that is often overlooked. Unless youre housing your components in a full tower case you need to research whether the card you want to buy will actually fit into your rig or not.

    Ive recently dealt with just such a case over on PCHF. The OP wanted to know whether the card he wanted to buy (an MSI N780 TF) would be compatible with his motherboard. The answer to that was pretty straight forward, the card would indeed be compatible with his ASUS P8Z77-I Deluxe, and his 600W was just scraping in as man enough to run the card. However, looking at the size of the card and the specifications of his case (Fractal Node 304) from the manufacturers website, it was a possibility that the card wouldnt physically fit. Below are the cards length and the specifications from the case manufacturers website. Not only is it just the case that needs taking into consideration, but the card may also foul on the PSU depending on the size of it.

    Another example comes from personal experience. I bought a rig last year that was to replace my old desktop rig, I didnt intend on gaming so bought an A10-5800k APU with an HD6670 GPU in a Cooler Master Sileo 500 case. After a couple of weeks I decided I wanted to game and the 6670 just wasnt up to the task, so I checked my PSU (400W) and found that the highest card it would run was an HD7850.

    I scoured the market and settled on an ASUS HD7850-DC2T and bought it straight away. However, when I came to fit it I found that I had to literally force it into the case with the end of the card sitting against the HDD cage. Below is a photo of the two cards side by side to give you an idea of the size difference you'll find between certain cards.

    The higher range of card youre going for will usually be a lot bigger than the lower and mid-range cards. Be 100% certain that your card will fit in your case.

    PART FOUR [/i] Compatibility
    Your CPU will also play a part in the choice of your GPU. Its not as critical as power requirements or the size of the card as it wont stop the card from working or fitting into your case, but an old CPU or lower or mid ranged CPU will bottleneck higher end GPUs. Most modern quad core CPUs will be fine coupled with modern GPUs, but older CPUs and dual core CPUs could well hold back the performance of your GPU depending on which GPU youve chosen.

    Again, its wise to check benchmarks online for your CPU if youre in any doubt.

    All modern motherboards these days come with PCIe 3.0 as standard, and all modern video cards will be PCIe 3.0 compliant. However, if your motherboard is an older model with only PCIe 2.0 slots available, your card will still work as the interface is backwards compatible. Its worth noting that the card will be capped to PCIe 2.0 transfer rates but it will still work.

  2. No Symbian 3 for Nokia 5800

    @Nishanthrao - This has been discussed several times before. Basically the core files of S^3 is written with a GPU and a CPU with a minimum power of 600Mhz in mind, the 5800 having no GPU and only 434Mhz CPU. Its like asking Windows 7 Ultimate to run on
    Win98 hardware.

    Won't set to a higher resolution

    OK, on your new system is the correct Display driver loaded, go to Control Panel - Device Manager and make sure that you are not running the Microsoft Basic Display Driver.

    If the correct Display Driver is loaded, right click your Desktop, choose Display Settings and see if your resolution is set to the one marked (recommended)

    If your resolution is set to the one marked (recommended), then I have some questions:

    • Does your new Computer GPU support higher resolutions
    • What size is the monitor you are using
    • In the control panel of your GPU can you choose to set a custom resolution
