Upgrading RAM

Venomx999

Got an old-school Dell which i've been using for a few years now. Got it second hand in 2017 and did a few upgrades. Upgraded from 2GB of RAM to 3GB . Upgraded the graphics card, and upgraded to Windows 10.

I checked my usage via the task manager and whilst browsing the web my CPU usage goes very high ( 70 to 100% )
RAM usage is about 2GB out of 3GB so about 70%.

Am I right in saying that upgrading the RAM won't make any difference, but a new processor would ?

If that's the case i'll look into upgrading as I found some good'uns on Argos for around £300.

It's not imperative that I do any upgrades whatsoever, as for just browsing the web the PC suits me just fine. I'm just wondering for future reference ?

Thanks

You may want to check why CPU is at 100%, what is running on the machine at the time?

It sits at around 10% when not being used ( idle )
But when browsing the web it goes upto 80%, sometimes higher, then back down again  ( once the page is loaded )

It's a clean install on Windows with nothing installed other than chrome running.

Fast enough for me pretty much loads sites instantly.

You're more or less correct. Excess ram is used for stuff like pre-caching (superfetch) which can speed up the system a little but if you're already got 50% more than you're regularly using you're not going to see much benefit adding extra.
