Old PC graphic cards died, considering upgrading it a bit

RAM: 2x GSKILL Ripjaws Series 4GB PC3-12800 DDR3 DIMM Power Supply: Antec True Power New 650W Power Supply w/ Quad +12V, 120mm Fan Motherboard: GA-Z68X-UD3H-B3 w/ Dual DDR3 2133, 7.1 Audio, Gigabit Lan, 1394, CrossFireX / SLI CPU: Intel Core™ i5-2500K Processor, 3.30GHz w/ 6MB Cache Video Card: eVGA GeForce GTX 560 Ti FPB 1GB GDDR5 PCI-E w/ Dual DVI, HDMI

My computer is about 6 years old. My graphics card died and I'm running on its crappy integrated cards now. Not written is the spec is a 1 TB HDD, also about 5 years old.

I don't have the money for buying an entirely new computer so I'm wondering what kind of upgrades people would consider.

Mainly: I was looking at the GTX 1060, and to buying an SSD.

I was wondering if I should just add 2x 4 GBs RAM on top as well, apparently 8 GB isn't enough anymore.

And all in all, is this a good idea? My motherboard is as old as the computer, I don't know how sturdy these things are these days but I don't want it failing in a year.

I'm just looking for confirmations or other suggestions. I'd also like to know which SSD or which RAM you'd recommend me to buy with this system.

NOTE: Yes I'm going Nvidia, I don't want to debate that part. I do it for software-related reasons. If you have card suggestions, please keep it between Nvidia cards.
