* CPU is plenty for most peoples needs and can OC quite good too!
* CPU HSF is better than stock cooling and also can cool quite well for the $!
* GPU is better than the 660 Ti for the $ and can OC too, so it's up to you.
* PSU is plenty for any single GPU out there.
* Case comes w/2 x USB 3.0 ports (yours selected doesn't). Can handle up to 450mm GPU's!! 17.7" worth! Not sure if you really need a Full Tower case, because the one I listed will do the job well
