Your System's GPU

this topic can be very confusing, especially for those who haven't ever had to look closely at their computers specs. first off, GPU stands for Graphics Processing Unit, and can also be described as Visual Processing Unit. these chips, or GPU's, have recently gotten amazingly efficient in processing computer memory into a frame buffer, which are intended to display images/video feed on a monitor. the difference between an integrated and dedicated GPU is quite important, and it bugs me when people can't see the difference because it can mean the difference between lagging out of your favorite minecraft server, or destroying little kids in battlefield 4. integrated GPU relies on the resources of the rest of your computer, thus making it much more prone to slowness when it comes to graphically intense games, but can perform much better with office or email, which is what integrated GPU's were intended for. integrated means that it works with your CPU, which stands for Computer Processing Unit. Integrated chips are generally considered week and incapable of doing anything other than work or browsing the web. on the other hand, dedicated GPU's are pretty much the exact opposite. they have their own Imbedded processor, its own allocated set of memory. but unlike the integrated GPU, this memory and processor is reserved strictly for the graphics card, which makes it worlds faster than an integrated GPU. you could think of it as its own tiny yet powerful mini computer. But unlike the integrated GPU's, these are much more powerful, and no matter what integrated graphics card you could find, hands down dedicated GPU's will always perform better. dedicated GPU's are primarily used in gaming computers. Integrated GPU's are usually found in laptops/desktops designed for work, for example, the Dell Inspiron 15r laptop. Now I have to warn you, some companies out there are misleading consumers on what type of GPU they are receiving. ever since gaming has been becoming more and more popular, there are a select few companies that are telling consumers that they are receiving dedicated when in reality they are receiving integrated. this is because integrated GPU's are becoming less and less popular and companies are finding them harder to sell. So make sure that if you are purchasing a computer, its from a well respected dealer, or you know what your getting. If your planning on doing some light gaming, such as minecraft, the modern warfare series, or war thunder, all while getting work done or using it for school, a dedicated GPU is not necessary. especially not if your buying a desktop. with a desktop you can always switch out the CPU's and GPU's, and just about everything else. but if you have a laptop, your going to want to look into it more for the long term of what your wanting to do because unfortunately with laptops, it will be impossible to change out anything.

Your Systems CPU

the CPU plays a large role in your experience with your computer. this also ties into what your wanting to do, but when it comes to CPU's, this really depends on your budget, because if your planning on using it for work, its not going to matter whether or not your running an Intel core i3, or the latest Intel core i7, unless of course your running complex computer algorithms or trying to demonstrate anything that would require a ton of "computer horses" to render or to display something. now if your gaming, the latest i7 would be fantastic. add that into the latest GPU and your on your way. but if your on a budget, the latest or at least a recent i5 should be ok for most games. Games such as DayZ run almost entirely off of your CPU. so if you have a good CPU but a not-so-great GPU, running games such as DayZ shouldn't be a huge concern.

The amount of GHz in your Systems CPU

A great way to tell if your CPU is of quality to look at the amount of GHz it has under the hood. GHz stands for Gigahertz, giga means billion and hertz means frequency. The amount of GHZ your computer possess determines how fast it can process things. Further more, the speed, or the number of GHz you have is directly influenced by your processor. an old Intel Celeron may have 2.8 GHz, but a newer Intel i5 processor that clocks in at 2.0 GHz will run much faster, despite the fact that the older GPU has more GHz. its confusing, but as long as you stick to newer processors, you should be ok. that's if your sticking to work. the number GHz you want may also depend on your OS. (for noobs that's Operating system) Whether it be Vista, or Windows 8, the effectiveness of your processor and GHz and just about everything else may be effected. for Vista you'd probably need around 1.8 GHz for the OS to be run properly and smoothly. if your on XP, 2.0 GHz is around the safe zone. keep in mind that is just the bare minimum, so don't expect for your computer to run graphically intense and demanding games. Now if your processor is a dual core, or a quad core (4) then your GHz is multiplied by the amount of cores you have. so if you have a dual core 2.0 GHz processor, and the game or OS you want to run requires lets say 3.0 GHz, don't worry, because the real amount of GHz you have is 4.0 GHz. this has caused much confusion in the past so I just wanted to make that clear for anyone who may have been worrying about their computer not being able to play their newly purchased game.

      CPU stands for central processing unit, not computer processing unit. I stopped reading here.
