Beginner’s Guide On How To Choose A GPU

Its not easy to choose a GPU for your PC as not only you have to take into account just how good the GPU itself is, but also how does it go with the rest of your gaming rig.Does it Bottle neck your system ,does it cause any overheating issues, is it bang for your buck, is it too big to fit into your case and so much more.All this makes it much more harder for you to choose a GPU and you can easily find your self overwhelmed .So in today’s post I will go through everything you need to  be vary of when you choose a Graphics card for your PC.

Does The GPU Bottleneck My CPU / Or The Other Way Around

This is probably the first thing to look at when you choose a GPU for your PC as any sort of bottleneck means money wasted on power that you can’t even use. Now if you don’t know what bottleneck is than here’s a quick overview;

Term “BOTTLENECK” refers to when either one of the 2 components (your GPU or the  CPU) may not be powerful enough to make full use of the capabilities of the other. What this means is  your CPU maybe at 100% usage but the GPU may be underutilized. As a result despite having a really good GPU you would suffer from FPS loss in games or you simply  won’t be able to run them.

On the contrary this could also be the other way around. IT may be so that your CPU may be good enough to actually handle a certain game but your GPU may just not  be as good.In such a circumstance your GPU that’s responsible will limit  your frames per second.

Now to avoid this I suggest you head over to https://pc-builds.com/calculator/ .PC builds calculator allows you to  check if there is going to be any bottleneck between your CPU AND CPU. Simply select your GPU and CPU from the menu and hit calculate .Anything over 10% bottleneck is bad.

POWER

When you choose a GPU you need to keep a close eye on how much power does it need to function at its optimum.If your GPU is under-powered it can cause problems within your system, such as your graphics quality may drop or your GPU performance in general may be poor.It can also damage your power supply by overdrawing power . This puts other PC components into the risk of getting damaged as well.  A 600 w power supply is enough for most GPU out there and that’s what I would recommend.

COOLING

Some GPU’s struggle with overheating issues due to poor ventilation system.The heat produced by the GPU   is represented in TDP value. If your TDP is too high you run into risk of overheating and damaging the components. To tackle this you would need more fans for proper air ventilation.What i suggest is you read other people’s reviews before you choose a GPU.This would help you find out if the GPU has any flaws and avoid having to spend extra money on fans.

CLOCKSPEED

Every GPU has a clock speed measured in MHz.Your clock speed tells you how quickly the cores of your GPU render graphics. A higher clock speed means faster cores that in turn render quicker and process information faster.Clock speed is a very important aspect of your GPU.One you should keep a close eye on when you choose a GPU.

OVERCLOCKING CAPABILITY

Overclocking as the name itself suggests means increasing the clock speed of your GPU higher than  what it was initially designed to run on by the manufacturer.  Overclocking allows you to increase your GPU’s performance and improve your gaming experience in general.It is  completely safe if done right However it leads to higher power consumption and greater TDP . Almost every GPU is capable of being overclocked however by how much depends card to card.So buying a card that has higher overclocking capability will allow you to get more out of your system however it would also cost more .

VRAM SIZE

VRAM size can vary anywhere from 2 GB to up to 12 GB.Your GPU RAM decides how quick GPU can access information being sent out by the game.So greater VRAM means faster access.How much ram does your GPU needs is debatable. However i would personally choose a GPU with at least 4 GB of VRAM. 

PRICE

In the end it all comes down to which is going to be better bang for your buck. AMD and NVIDIA both have equivalent GPU’s in each tier .Before you choose a GPU just search up the equivalent card of the other company and compare the price tag.
