Intel

660ti is not worth saving. Need a new mobo, cpu, ram and gpu, go for past 10 series intel i5 and atleast the 1650. Rk 1070/1080 is fairly cheap used and still does good work. you are looking at about 400$ of upgrades

wtf? that's like a $20 video card, intel integrated graphics are probably better at this point

I see your point, I really don't like leaving my old pc parts laying around collecting dust either, what I do is take my previous pc parts, put it together as Budget Builds then dump them off to Family and Friends whom do not know how to build pc's, works like a charm :P Seriously, I do usually give it to them for Free though.
To better answer your question:
Your i5-3470 is a 10+ year old platform using only DDR "3" Ram, that platform is getting too old to bother with.
I looked into Bottleneck, that 660 Ti is already to weak for that 3470, So....
A couple comments I've seen in this Thread could help you to not have to throw it all way.

1. That 660 Ti is pretty much too old, but that 3470 can still effectively run a 1650, replace 660 TI w/ 1650.
2. SSD, If you've never owned an SSD you will be super impressed in how much faster that alone will make your PC, a whole lot, even with nothing else upgraded. You will have to re-install Windows onto that new SSD. A 2.5" 1TB SSD for about $40 on Amazon would do fine.
