Upgrade. Your thoughts. GPU or PSU + SSD?

[selianx]

Hello there.
The system i'm running is :
CPU - AMD Phenom II X4 965 BE OC'd 3.8Ghz - Cooler Hyper TX3 EVO
GPU - Asus GT 640 2GB DDR3
RAM - G.Skill Ripjaws 8GB 1333MHz (2x4GB)
MOBO - Gigabyte GA-970A-UD3
HDD - Barracuda 7200RPM 500GB
PSU - CM GX 550W

I'm planning in the next months to do the following upgrades.
A GPU, an SSD and a good PSU, coz I've seen many posts of this CM GX 550W being a suck-ish one (tier 4).
So my budget is right now at about ~220 euros.

Should I get a Tier 1 - 2 PSU and an SSD for these money and get my GPU later, or just upgrade my GPU now and later the PSU and SSD? What would you guys do.
I don't want to buy a new GPU and then fry it because my PSU sucks hard .

BTW, I'm between R9 270x , GTX 760, HD7950 as for GPUs.

For SSD I'll get a 128 GB Samsung 840 Pro.

For PSU, which one would you get?
Corsair Enthusiast Series TX650 V2 80PLUS Bronze (Non modular) (85 E)
XFX ProSeries 750W XXX Edition 80PLUS BRONZE (Semi modular) (106 E)
Antec HCG-620M 80PLUS BRONZE (Semi modular) (95 E)
Seasonic G-550 80PLUS BRONZE (Semi modular) (114 E)
Corsair RM Series 550 80PLUS Gold (Fully modular) (102 E)
XFX ProSeries 750W XXX Edition 80PLUS Bronze (Semi modular) (101E)

Any other recommendations?
Thanks in advance.

depends on what you use your computer for, if its for gaming then you should either get a 760 or a 270x. if you do video editing or other heavy programs then an ssd would probably do what you need.

no need to upgrade your psu until you see an issue. gpu and ssd would probably be the best upgrade if you can swing it.
