Buyer’s Guide

– What are LGA 1155 CPUs?

LGA 115 CPUs are the Central Processing Unit. CPUs are found in just about every piece of tech that you have and they are crucial to performance. They are responsible for processing and executing instructions that you give and the computer give.

There are a few different parts of the CPU that you should know before you start the process of buying one.

They are:

    • The Socket: This is the component on the keyboard that connects the motherbaod and the CPU. It is a physical and an electrical connection, so they have to be compatible.
    • GHz: Short for Gigahertz, this is the rating that shows the frequency of cycles per second. Typically, 1 GHz represents one billion cycles in every second. A cycle is when the CPU gets instructions from the software and executes said command.
    • Turbo Boost: This is a feature the helps to achieve the maximum potential speed for a particular CPU. This is aligned with the thermal and electrical limits of the CPU.
    • Core: The core is formed by the CPU. This means that if you have a Dual Core, you get two combined CPUs. A Quad Core is four CPUs. In general, the more CPUs, the faster and better it is.
    • Data Bus: A CPU’s data bus is the passage through which the data is conveyed among peripheral mechanisms. Data has to move quickly, particularly when gaming, for there to be any congruence. There will likely be a number of data bus systems.

– What Matters For Gaming, In Particular

If you are buying the LGA 1155 CPU for gaming, in particular, there are a few different things that you will want to think about.

They include:

  • Socket Compatibility: Compatibility is the primary aspect that you should be concerned with when buying a CPU. This ensures that the CPU and motherboard are able to connect and stay compatible. This is essential.
  • Frequency: The speed of your CPU is important while you are gaming. It is believed that the faster you can refresh, the better your performance will be, particularly in graphics-heavy games. You want to find a CPU with a quicker processor.
  • Cache: The cache of a processor is the same as the memory. This is a smaller and faster memory that is used for short-term storage. It allows the machine to recover when the cache crashes and make everything easy to grab. The bigger the processor’s cache, the more data can be stored for a faster recovery, which is necessary when you are gaming.
  • Thermal Scheme Power: This is a key feature that is assigned to describe how much heat the processor gives off. This will impact the cooling necessary for the CPU. If it does not come with a cooler, then one needs to be added. Overheating will surely impact the lifetime of your CPU.

Quick Tips For Buying The Best LGA 1155 CPU

Still a little bit lost on buying the best LGA 1155 CPU?

Here are a few other tips to keep in ind as you start your search:

  1. In general, unless otherwise noted, you want to buy the latest gen in a line. There are some situations where this isn’t the best option, so that is noted.
  2. If there were ever a place to splurge, it is going to be on the CPU. Save up for it.
  3. Remember to think about the additional accessories that you will have to buy to get the most out of your motherboard and your CPU.
  4. In many cases, you should pay attention to clock speed as much as you pay attention to the number of cores that a CPU has.
  5. Overclocking will shorten the lifespan of your components, so you want to get something that has a good cooling system.
  6. Noise is only a problem for most people who are gaming or those who will use mics to talk to other players. If you fall into this category, it will matter to you.
  7. When in doubt, look to the graphics performance of your rig.
  8. If possible, try to stick with Intel products.
  9. Remember that bigger name manufacturers will have much more customer support and online support should you get lost.
