Should I upgrade? (my system vs Q3 2013 build)

Hey guys I am wondering if now is time for me to upgrade. I know my GPU is out of date but I'm not sure about the rest.

My system was initially built in 2010 to run StarCraft 2 and the reason why I selected the CPU I did was because there was, at the time, reports of it being able to hi 4-5 Ghz OC.

First I would like to know if my system is comparable to the second system listed which is a Q3 2013 build.

Secondly I would like to know how my system would hold up over the next year if all I do is OC the CPU, replace the GPU with say an R9 280x which is my GPU of choice ATM and if my PSU should be upgraded.

Third, and this is unrelated to upgrading, I'd like to know what kind of difference my system OC'ed to say 4~Ghz and a modern system with a CPU already at 4~Ghz everything else being the same.

Unfortunately, your CPU is quite a bit slower than the i5-4670k: http://www.cpu-world.com/Compare/453/Intel_Core_i5_i5-4...

These are at stock speeds however. If you OC that 750 to over 4 GHz, you would narrow the performance gap quite a bit. That should get some more life out of this CPU. An R9 280X will do most of the heavy lifting for your games, and that 550W PSU does have enough power for this setup.

For your 3rd question, your system will be somewhat slower at the same frequency than a modern system due to improvements in the CPU architecture. Intel typically states their new architectures are about 10% faster at the same clock speed than the previous architecture family. Here is an example of the Ivy Bridge 3570k vs the Haswell 4670k (both 3.4 GHz): http://www.cpu-world.com/Compare/579/Intel_Core_i5_i5-3...

How many gens behind is the Lynnfield to the Haswell?

It's 4 gens behind. Also, the next gen, Broadwell, may be out by this time next year. It is 14nm vs Haswells 22. So it will be next gen manufacturing process as well.

Here are 3 options;

1. Build a new rig with middle of the ground GPU like a GTX 760

2. Use all the money in option 1 and just get a R9 280x or R9 290x and OC the i5-750 to 3.4-4Ghz.

3. Suggestion by you.


Care to guide me through putting some sense into my three options so I can make a good decision on what I should do?

It's really up to you and comes down to how much money you want to spend. Upgrading just the GPU and overclocking will be less costly than building all new. You may want to upgrade the PSU if you do a heavy overclock as you will be near its max capacity of 550w, but I don't know for sure how many watts the OC would add. Maybe someone with OC experience would know (I've never done it). You will also need to upgrade the cpu cooler if it's stock. You did buy the chip with plans to OC, so maybe now is the time. It should work fairly well. Do some searches on the web about overclocking that chip. Maybe there are some benchmarks using current games.

If money is no issue, then build new. It will perform better and last longer than upgrading your current rig.
