New Mother Board Ram & CPU

Weaver:
I would also say that high core counts are worth nothing unless you either

1. have the right apps that are internally multithreaded, which is horrifyingly dangerous for the programmer in terms of potential bugs if you get it wrong and sometimes onerous too, or

2. have a setup where you do regularly run multiple processes in parallel that compute. Many processes are io-bound, waiting on the user, in the network or on the hard disk or other storage device.

3. Some computing processes are very hampered by the incredibly slow RAM that we have to out up with nowadays, where RAM has fallen further and further behind CPU speeds, my rough guess would be by a factor of 50:1 - 100:1 nowadays compared to the speed of RAM in the early 1980s. This kind of computing, where a lot of RAM accesses are just essential and nothing can be done about it - because it is just the nature of the job that needs to be done or where caching is ineffective, possibly because if a badly chosen algorithm or just because of bad luck, again the particular situation the application is in - means that a fast CPU won't help, won't be able to shine.

Hence my question regarding higher core count or single threaded performance.

I've had a 6 core Intel system at 4.5Ghz for a long time now, it's great when transcoding video.

I put together a cost for an a 6 core i5 8400 cpu motherboard and 8GB ram and that came to £357

I've done no research on the motherboard, it was purely to see what the cost came to, it may also be cheaper elsewhere.

Whilst the 8400 cpu performs a lot better than the 2400G, the integrated gpu is leagues ahead in the AMD cpu.

Most of what I do now is Web browsing and have a wee bit of money to spend on myself for once Ronski yet this old Asus E6700 with with Nvidia 650GT does what I need just thinking of cheap upgrade, When looking online for a whole new tower and cpu ram & os it all seems very expensive these days ranging from £399 low spec to gaming £1000  :o   

Weaver:
I would tend to prioritise a superb SSD drive and plenty of excellent quality RAM first then think about CPUs if it were myself.

BTW, You are using a 64-bit o/s of course, I presume (64-bit is absolutely essential), but then I am so out of touch that probably no-one does any other these days.

Ronski:
If most of what you do is web browsing then the 2400G would be more than enough, to give you a comparison here's the 3 processors.

https://www.cpubenchmark.net/compare/Intel-Pentium-E6700-vs-AMD-Ryzen-5-2400G-vs-Intel-i5-8400/1106vs3183vs3097

As you can see the 2400G is almost 5 times higher in the performance rating than the E6700, and the i5-8400 is 6 times, this is multi-threaded, the single thread rating is not so high.

I would recommend nothing less than four cores though, as it simply allows the OS to be more fluid - there's many processes going on in the back ground.

Weaver has made a very good point, a decent SSD or M2 drive would make a bigger difference than a substantially faster CPU.

What HDD do you currently have, also what is the occasional intensive GPU requirements?

What OS are you using, if Windows is it retail or OEM?
