Help with PC upgrade

[DaarkGhost]

Hello everyone, i have about 450$ and i wanted to have something better for my pc (could be just one thing)

Current rig:

Mobo: MSI H81m-p33
Ram: 8GB DDR3
CPU: i5 4460
GPU: Asus GTX 750 Ti
PSU: Coolermaster 700 watts - (B series, v2, pretty solid imo)
Case: NZXT Noctis 450

Screen: standard samsung screen 19" (923NW for ref) with a max res of 1440x900

I'd like to hear your suggestions about upgrading? I play a lot of dota2, but i also enjoy playing all kind of different games out there.

gtx960 when the price comes down (after gtx1070 hits retail) and an ssd if you wanted one.
