Upgrade or not upgrade, to be or not to be?

[R2-D2]

I was wondering if I would benefit from upgrading to a new CPU and consequently motherboard. I have a first generation Core-i7 Intel CPU, which is close to 5 year old now. Besides general office work I play games on my computer.
I don’t know if this upgrade is going to make a difference. I don’t seem to have any problems playing new titles on high settings with this old generation CPU. But then of course, I have nothing to compare to. At least what I do know is that my current motherboard lacks SATA 6Gbps support required for my SSD.
If I’m going to upgrade then the obvious choice for me is one of the new Haswell processors and I wouldn’t mind getting the latest and fastest i7 4790K (so called Devil’s Canyon). This of course would require Intel’s new 9-series motherboard. But Haswell processors are not entirely new, they are “refresh” of existing architecture and are still built on the 22nm process. And now we hear about arrival of new Broadwell processors built on the 14nm lithographic process.
So what would you recommend, upgrade now or wait for these new Broadwell processors?
My current system:
CPU: Intel Core i7-860 (45 nm Nehalem, 8MB cache, 2.80 GHz, 4 cores, hyper-threading)
Motherboard: Asus P7P55D Pro
Graphics: 2 x Radeon HD7870 Tahiti LE (CrossFire)
Drives: Intel SSD 330 180GB, Western Digital Caviar Blue 500GB
RAM: 2 x 4GB Corsair Vengeance Dual Channel
PSU: be quiet! Power Zone 850W

Why use such small font print? Just type no need to get fancy

If you don't feel a need to upgrade because your not struggling to play games then don't upgrade and wait. If you want to upgrade then get the best thats out now. No sense in waiting as something new will always be around the corner.

The 4790K would be a very nice upgrade for you especially if you're an overclocker. You'd be looking at around a 20-25% improvement if I remember my benchmarks from back then. Yeah Broadwell is coming out soon but there is ALWAYS something newer and better coming out soon. No matter how long you wait, there will always be something better around the corner so buy what you need when you need it.

As others have said I would highly recommend getting the best you can right now, If you wait for new releases you will end up putting it off and off as there's always something better on the horizon.

in the same boat as you pretty much, at the moment im still running my i7 980 6c/12t @3.9 ghz ,on a asus rampage 3 black edition. (x58 chipset)
don't seem to have any problems in the newest games
but i would like to upgrade to get some of the features from the newer chipsets.
always feels like im waiting for a successor to the x58 chipset
