Overclocking questions on my massive bottleneck PC

Hi, I've got a pretty old PC. My motherboard is an M3A79-T Deluxe motherboard, AMD Phenom II X4 940 processor, 16 GB of DDR2 memory; the only new part here is my video card which is the Radeon R9 270X Sapphire 4 GB OC edition. I will hopefully be upgrading the processor and other parts this coming February but here's what I've been wondering until then: Should I overclock my parts at all? Well I already have overclocked both my GPU and CPU. The default core clock for my video card is 1070 Mhz and I bumped it to 1154 but for some reason it feels slower now (maybe not slower but around the same). The default memory clock speed is 1400 and I bumped it to 1450. Should I even bother to overclock or should I put it in a "sweet spot" range? My processor is quad core with 3 GHz but I overclocked it to 3.3 GHz and it seems okay. The temperatures are perfect btw. On Battlefield 4 my CPU goes to like 50 degrees and GPU goes to 50-60. Essentially what I'm asking is how much can I overclock my CPU to and how much can I do my GPU? Any help would greatly be appreciated. Thanks. BY THE WAY. My power supply is an 800 watt but it is somewhat old but it also runs very cool and well.

Trial and error is really the only way to know just how much voltage is needed. Bump up the multiplier and increase the voltage only when it fails to run stably.

The only way to know how much you can overclock is to over clock it.

If there was a known max overclock on a CPU people wouldn't spend hours inching it up and testing. They would just look up the overclock and put it on.

Everyone piece of hardware is unique and has its own limits.

Just keep your temps and voltage in the safe area and keep at it.

Overclocking headroom varies a lot depending on your individual chips, your motherboard, and your cooling. You could probably overclock your CPU more: 3.5-3.9 should be possible.
Here is some info on what different 270x models were able to achieve: https://www.techpowerup.com/reviews/MSI/R9_270X_Gaming/27.html

Rather than relying on a subject test of what feels faster, you should benchmark your system at different overclocks so that you can compare. Many games have a built-in benchmark you could use.

Thanks for the replies. Right now I've overclocked it to 3.4 GHz with the default voltage. When and how much should I increase the voltage by? I've heard messing around with the voltage can do a lot of damage if not done correctly so I'm just wondering. I also decided it would be perhaps best to leave the video card be for now until I upgrade the other parts. Besides, out of all parts, the processor needs it the most. So any idea on how much voltage will be needed for the range 3.5-3.9? Thanks
