MSI GeForce GTX 960 Gaming 4G will work?

[miguitar]

Intel core i5 3570-k
Gigabyte Z77P-D3 mainboard
16 GB DDR3
Antec Vp450P power sypply
MSI GTX550 ti

I would like upgrade gtx550ti, becouse is not working well, too slowly, with video editors like Cyberlink Power director 15. Will work GTX960, well? or can you tell me what card would be the best option?
Thanks!

A gtx 960 would be nice step up but I would get a GTX 1060 if you can afford it. The jump will be much nicer and your CPU is capable. However I would get a new PSU regardless. It's of poor quality and I would not encourage you to use it much longer. You want at least a tier 2 PSU (if willing to replace of three years) or a tier 1 (if willing to replace every 5 years). Yours is a tier 3 and not recommended.
