Does a slow pc impact your business?

A slow PC can seriously impact your business which translates to lost productivity and frustrated staff members. As computer hardware becomes more reliable, our preferred brands like HP and Dell systems can easily operate for four years or so.

However, the demands on modern IT systems are ever increasing. With the introduction of Windows 11, Microsoft 365, and other key line-of-business applications, your computer systems face greater strain on Processor (CPU), memory (RAM) and Storage needs. The issue though is that your slow pc is more often than not the same specification that it was on day one and is therefore simply put; struggling to keep up.

Slow PC

When clients want to replace their slow pc or add to their suite of business machines, sizing the PC can feel overwhelming. However, we can simplify the process by breaking it down into understandable sections.

Business Applications

Firstly you need to consider the business apps that you use. These most likely consist of Microsoft Office, Sage Accounts (or similar) and possibly an ERP or CRM product. Each of these apps will have a minimum recommended spec for:

  • Processor
  • RAM
  • Storage

For CAD users, there will likely also be a specific graphics card specification.

The vast majority of business applications will ask for a 2ghz or higher processor, 4Gb RAM and 10gb+ storage. Whilst you do not need to strictly add each apps requirements together, there will be a cumulative total overhead.


The speed of a Processor (CPU) depends on several factors, such as the number of cores, the clock frequency, the cache size, and the architecture. The simplest way to think of it as follows:

  • Intel i3 for entry level users
  • Intel i5 for mainstream users
  • Intel i7 is for high-end users


The amount of RAM (memory) you need / desire is dependent on your applications and of course budget.

For basic web browsing and document creation, we now recommend that 8GB is usually sufficient. For tasks such as photo editing and multi tasking however, 16GB of RAM is increasingly becoming necessary.

CAD or video editing applications will require even higher amounts of RAM (e.g., 32GB) to ensure optimal performance.


The vast majority of users will get away with an entry level 240gb storage. Those that need to save a higher volume of documents locally or have access to shared mailboxes or a shared Drop Box may want to consider opting for a desktop that has at least 500gb local storage.

Other considerations

Other considerations include the operating system and do you need one, two or multiple screens.

With the scheduled retirement of Windows 10 due for next year, we recommend that all new pc’s are loaded with Windows 11 Professional.

When it comes to screens, there are studies that claim a 21% productivity boost by having more than one screen. Here at Hobb Computer Services Ltd, we believe that most users do indeed function best when they can view two apps side by side. This can either be achieved with two screens (we recommend 24″) or better still with a single 32″ (or larger) screen. In most cases, a single screen is budget friendly when compared to 2 screens and a dual monitor arm.

Hopefully the above helps when sizing a desktop pc but of course if you need assistance then please reach out to your normal contact or email us at
