Is upgrading even worth it?

A while back I reached out for advice about a build I was planning to do (I got some great advice). ALAS the budget for that system was used to make a down payment for a desperately needed automobile....that being said: I'm currently running system I built back in '09, and the funds to build a new system just aren't there. I'm curious if upgrading this old system is even worth it.

Current Specs:

Asus M4N98TD EVO

Geforce 9500 GT X2

8GB DDR3

AMD Phenom II x2

WD 1.5Gb 5400rpm x3

Corsair HX750 PSU

I'd Like to upgrade the CPU, Graphics Card, and perhaps replace one of
the HDD with an SSD(I'm sure that will make a huge difference)

Upgrades:

AMD Phenom II x6 1090T or 1100T

Nvidia GTX 950 (or something better? sub-200)

and finally an SSD of some type....

I'm just looking for thoughts opinions and suggestions....thanks

I would upgrade the GPU for sure.

SSDs are worth it, the rest is dependent on a lot of factors and might require a full upgrade. Best thing to upgrade an old system is change the OS. Are you on Windows?

So, what's your new budget?

Windows 7 Home Premium

Probably around $400

The only thing I can recommend to upgrade right now with scheduled release of new hardware 12 months from now? SSD

If you don't mind picking up a Sapphire R9 270X then trading it in after a complete system rebuild using nearly completely new components that is also a decent option.

Maybe get a new power supply probably with the left over cash

if you can get a phenom X4 or X6 for cheap maybe go that route, the 860k isn't actually going to be much faster than them, but at least it's new

Maybe spend a bit more and get an 88X motherboard so you can overclock the 860K

This with an 850 EVO. You should be golden.
