Looking for a little upgrade

[Yo1998]

Please help.
I'm planning to give a little upgrade to my pc. Actually, i have this components:
Cpu: AMD FX-6300
GPU: Radeon HD 6670 1gb ddr3 (yeah, it's not good, but actually i dont olay heavy games)
Ram: 2x2gb kingston in dual channel at 2100-2200 mhz (i dont remember exactly)
Motherboard: MSI 970A-646
512gb HDD
650 watt Power supply

I NEED more space, so i was thinking on an ssd. Specificaly this one http://www.bestbuy.com/site/sandisk-ssd-plus-240gb-internal-serial-ata-solid-state-drive-black/3075012.p?id=1219570102967&skuId=3075012

I have about 140-150 bucks max to spend, but i prefer less. Do you think that it will be a great upgrade? What do you recomend? I dont think that the ram will be a problem because i dont use the lc for heavy usage. Altought, i need the pc to work perfectly for college. The heaviest programs that i use are MATLAB, INVENTOR, RHiNO 3D and like them.
Please help me!

A little extra question. Windows 10 (actually i have windows 7) will be a major upgrade? Like for general performance, including gaming.

sorry for bad english, it's not my native languaje

Thanks

Windows 10 visually yes a major upgrade but with the GPU you have not for games. I'm afraid DX 12 won't make that big of a difference to your aging card!
Windows 10 is a tiny bit more resource hungry than Windows 7 but for moderate usage 4GB is still enough.
And yes get an SSD.... it's the best upgrade you can get for normal day to day usage that doesn't cost a fortune. Also, I'd suggest something other than Sandisk. Got burned by their SSD

First of all, i'm so sorry for the negativa point.
I was looking at best buy because im not from USA and i will go there in a few weeks, and many frirnds yold me about this shop. Where i csn buy it online and send it to the hotel? Sandisk is really bad? Do you think that a graphics card like gtx 750 ti (140 bucks) will be a major upgrade?
Thanks
