Hardware bottleneck and upgrade

[Epodax]

Hi!

First of all I'd like to apologize if I've chosen the wrong sub forum to post in!

Now to my main issue, I find that my custom build is slowly starting to fall behind when it comes to new games. I'd really like to avoid that so I want to upgrade my PC so it can handle everything smoothly again. The issue is that I don't know which part of my computer is the "bottleneck" of my graphics lagging / game lag and I was hoping you could help me

I'm fairly certain that it is either the GPU or my CPU, I'll list my entire specs just in case I'm wrong:

Specs:
CPU: Intel i7 960 (3.2GHz 4 cores)
GPU: Gigabyte GTX 670 WindForce (2GB)
MBO: Gigabyte GA-X58A-OC
RAM: 16GB 1866Mhz Corsair (Currently only running with 1600Mhz)
PSU: Corsair 750watt

As saId, I'm fairly certain that it's either the CPU or GPU that needs an' upgrade.

Any help is welcome Thanks in advance

While your GPU has life left in it, going with a new larger GPU will show you large gains while gaming. Your CPU, while not the newest, still has plenty of processing power. Are you overclocked at all? Focus on the things you could carry forward to a new build down the road. IMHO, those things would be with a new GPU and an SSD. The SSD won't give you performance improvements while gaming, but the overall experience on the PC would be better. Look toward the GTX 970 / R9 280x or higher for a new GPU. A good budget minded SSD would be with the Crucial MX100 or Samsung 850 / 840 EVO.

I allready have a 250gb ssd from samsung evo 850 something. The entire idea around the.computer when i bought it was that i would be able to upgrade parts as they got too slow instead of having to buy a complete new computer.

I will take a look at the gtx 970 when i get home

A new GPU is your best bet. Your GPU is midrange performance, as its performance is about equal to an R9 270x or GTX 760.

@sadams04 - I forgot to mention that No, I'm not overclocked, so far I've not found it necessary to do so (This is also because I only just barely know how to do this on CPU and RAM. and I know the motherboard is made for OC but due to it being a LGA1366 socket which is now no longer made it was the only board available to me after my original died).

@logainofhades - My main bet was the GPU as well, but since I was far from sure, I'd hate to buy a new GPU and then find out that the obvious thing falling behind was the CPU, so I'm kinda relieved I only have to change the GPU for now, since as mentioned above, my CPU is a LGA1366 which is no longer made.
Any recommendations for an' upgrade? I want a GPU that can handle coming games at ultra
