gaming doesnt need even 8 gig of RAM , let alone 16 .
Cut the RAM to a 2 x4 gig kit

Trim the SSD to a 60 gig model and instal it as a cache drive . See Intel Smart response

Use the money you save to get a Radeon 7870


And ditch the Rosewill challenger . Its built of thin metal and cheap plastic .
At the same price there are better cases like the HAF 912 , Antec ONE , or CM 430 elite .
My choice would be the Antec because of the front USB 3 port

The seasonic psu is very good quality
