Should I upgrade my motherboard or not?

Hi,

I'm looking to build a new computer but I still have my old computer from a couple of years ago that I forgot about. My plan was to simply replace the cpu and gpu in it to save the time and money of building a new computer from scratch. The only problem is that the motherboard is very old, it is ASUS P8Z68-V LX and the socket is a LGA1155. I've looked at compatible processors and there are some good ones that are better than what I need, for example the Intel Xeon Processor E3-1245 v2. I'm building this computer for the purpose of gaming and was expecting to spend around £800-900 (but I can spend more if really needed). So my question is, is it better to work with this old motherboard and buy an old, but good cpu? Or should I buy a new motherboard and then buy a newer cpu? I'm not particularly good with computers so I was hoping I could avoid having to take the motherboard out. Thanks.

I would recommend you don't get that CPU. It is already end of life. If you are building a PC, build one with modern parts. Newer bits are more efficient. It is not just GHZ that matters but "work" done per clock cycle. Think of GHZ as RPM's; a fairly meaningless value telling you very little about the horsepower.

If you aren't very comfortable building a PC yourself, there are shops which will do it for a nominal fee (typically 100-150 or so). Do you have a friend you could bribe to help you? Have you looked at amazon and other resellers to see what your money can get you in a new prebuilt PC? Your budget should be sufficient to get you a decent (although not top of the line) gaming PC.

The motherboard isn't the best it could be upgraded,there are better 1155 motherboards out there,cheap too. I would advise to go with a newer generation of cpu's but if you want to stay to the 1155 socket go with an i5 2400.You should know that since we are talking about the second generation of processors newer games will have a hard time on the cpu

depends;
what OS are you running? if windows 7 newer hardware you are going to be hard pressed to get 7th gen stuff to run windows 7. If not then i would be upgrading the hardware to a 6th or 7th gen intel, or new ryzen. M.2/NVME, USB Type-C, Thunderbolt, are just a few of the newer features that are worth moving forward on. Im running a 4th gen Intel core i7 devils canyon and I'm as well looking into building a new pc ( specifically for gaming though ) as i still use windows 7 for productivity.

Gaming wise if your not looking to do any productivity ( adobe premiere, Auto CAD ect..) Then a core i5 is really a sweet spot for the proc that your going to want for gaming. Or the ryzen 1800x.

Hi, thanks for the reply. The reason I picked that CPU was just more looking around on CPU benchmark. What I'm struggling to understand is, why is an old CPU necessarily a bad one? I was thinking that I could just buy an old CPU that is just as good as many new CPUs and there wouldn't be a problem. Instinctively it seems like it's a bad idea to use the old motherboard + CPU but I can't find any logic to confirm it because as far as I'm aware, if a CPU is good it's good, it doesn't matter when it was brought out? Thanks.

Put in simple terms older CPUs do less work per clock cycle. That is they do less work than a new CPU with the same GHZ. They also run hotter (more electricity to do less work).

If the old ones were just as good, we'd all be running them. There are numerous comparative reviews. Maybe read a few?
