Worth upgrading my CPU?

[peeps]

Just wondered what peoples thoughts are on this setup and if it's time to upgrade my CPU and Mobo if required. I wonder if my CPU might possibly be holding me back in certain games.

CPU: Intel Core i5 750 @ 2.67GHz (I've "overclocked" this using the smart 6 program that comes with the Gigabyte motherboard to 3GHz but understand this isn't "true" overclocking)
CPU cooler: Cooler Master Hyper 212 Evo CPU Cooler
GPU: Nvidia Geforce GTX 660 ti (MSI power edition 2)
Motherboard: Gigabyte GA-P55-UD3 (rev 1.0)
PSU: can't remember exactly but believe it is a Cooler Master 620W
SSD (for OS - Windows 7 professional 64 bit): Crucial CT064M4SSD2 64GB m4 2.5-inch SATA 6Gb/s (SATA III) Internal SSD
HDD: Western Digital WD1002FAEX Caviar Black 1 TB 7200 RPM
RAM: Corsair Memory XMS3 Classic 2 GB DDR3 1600 (x4 i.e. 8GB total)

I run my resolution at 1080 and the majority of games I can run at high at least with a decent framerate (but understand that there are way more powerful GPU's out there). Some games I really struggle to get a decent framerate though e.g. Arma 2. I get around 25-30ish frames on low/medium where a friend with a GTX 560 ti is getting 50ish frames with higher settings (but he has a better CPU).

So really, will an upgrade be worthwhile? Will I see significant performance improvements or actually will my current CPU last me for a while yet?

Sounds like you may need more performance, and that performance needs to be coming from your cpu.
Before you consider going ahead and upgrading, try and OC to 4Ghz or even 4.2 if you can reach it safely. I'm not really a fan of OCing through a program, but it's more user friendly to those who are unsure of tweaking through BIOS.

But try 4, and see if that helps you.

Thanks for the response. The smart 6 program will only allow me to overclock to 3.2Ghz (I think that's what I've got it set to actually, not 3Ghz as originally stated). You can basically choose between 2.8, 3 and 3.2

I'm not confident enough to try proper overclocking in the BIOS to be honest hence using the program.

Well some games definatly require more processing power then others..gaming at lower resolutions will also put a heavier load on the processor. 3.2 is not terrible but I could see it hurting your fps in some instances. First does cpu-z show your cpu running at 3.2 or 2.67? 2nd while gaming is your cpu at 90-100% load?

I honestly think you should try a real overclock its not that hard..not as scary as it seems at first. But if you absolutely refuse then yea would see gains in a cpu upgrade
