How To Choose The Best LGA CPU For The Right Price

The CPU determines the performance of the desktop. So, if you’re looking to upgrade your processor, you have to make the right choice.

Here are some of the factors you should consider before picking your LGA 775 CPU

The intended use:

What do you intend to use the new processor for? Why do you need an upgrade on your existing processor?

If the primary reason you’re upgrading your CPU is to send emails, watch movies, or browse the internet, then there is no reason to get the powerful processors. 

However, most people may begin by using their desktop for lighter tasks and switch to highly demanding tasks later on. If you’re in this category, feel free to go for a powerful processor. 

If you’re an avid gamer, programmer, video editor, and graphic designer, then you have a better reason to choose the powerful processors. But make no mistake; you might not need such powerful processors if you only play non-demanding games.

It’s time-consuming and frustrating using a desktop with a slower processor for a highly demanding task. And since you’re here, we believe you’re either a gamer, programmer, video editor, graphics designer, or someone whose job requires using a powerful processor. 

Availability of a cooler control system

When diverse software is running, or you’re tackling highly demanding tasks simultaneously, there’s a tendency for your desktop to overheat.

The heat increases with the more loads you add to your desktop. But this shouldn’t be a problem for a top-rated processor.

The thing is overheating can make you sweaty and uncomfortable while working with your desktop. And you surely don’t need such when playing your favorite game or working on that special project. 

So, when choosing your CPU, go for one that boasts a cooler or a specialized fan dedicated to tackling overheating. Yes, you can get an LGA 775 CPU with such features. They boast features that keep the computer system cool at all times. 

Please note that fan and thermal paste, in most cases, aren’t included in the CPU. In such a scenario, you may have to purchase these components separately. 

What’s your budget?

So, how much are you willing to splash on a new CPU? Are you planning on blowing your budget just because others claim that higher processors cost more? 

While higher processors may cost more, you can get a processor that meets your need at a fair price. 

Since you already know what you want to use the processor for, identify the CPUs in your ideal price range and note their individual features. 

Compare all the CPUs in your list of options and choose the one most suitable for you. One thing you shouldn’t forget is that you don’t have to blow your budget to have the current processor in your computer system upgraded. 

Just know the intended use and the processor’s features. With these, you can gauge the new processor’s performance and pick the right one for you. 

Understand how the CPU performs

Now that you have picked the processor you’ll be upgrading to, you should take out time to understand how the processor operates. 

If you’re a gamer, find out how features like the CPU core count and clock speed can impact your gaming experience or other CPU-intensive tasks. 

Now let’s throw some light on both features to enable you to make an informed decision. 

Let’s start with the CPU Core Count. One thing about modern CPUs, particularly those built for highly demanding gaming tasks, is that they boast multiple cores. 

What’s more thrilling is that each of the cores behaves like extra processors, making it possible for the CPU to simultaneously respond to multiple instructions. 

So, if you plan to use your computer system for multiple tasks, you’re better off with a CPU that boasts a higher core count. 

With such a CPU, you can be streaming gameplay and playing at the same time. 

So, have at the back of your mind that CPUs with multiple core counts are better at handling multiple tasks than one with a single core count. If you have a higher workload, such CPUs are a wise choice for you. 

Next is the CPU Clock Speed. 

CPU clock speed is also referred to as frequency or clock rate. It talks about the number of cycles a processor can execute per second. 

Again, CPU clock speed comes measured in Gigahertz (GHz). And you can find modern CPUs that are executing billions of cycles in a second. 

The clock speed of your CPU is crucial and can impact your gaming experience. So, ensure you look for the highest core speed when choosing your CPU. 

You’re better off with a CPU whose clock speed per core is higher.

The graphical quality and power consumption:

Modern CPUs make gaming and doing other CPU-intensive tasks enjoyable. With the HD image quality, you might be tempted to spend a whole day playing your favorite game or working on your computer system.

Choose a CPU that can deliver HD image quality when playing a video game with HD graphics. 

Furthermore, the smart energy-saving feature is another crucial feature to consider when choosing a CPU. It helps conserve energy, so your computer system can stay on for a long time to get your tasks done. 

If you happen to find yourself in an area with no power supply, you will know how crucial the smart energy-saving feature can be.
