Go with a Radeon 7850 over the 570 - it gets better numbers and is far more energy efficient.
Is the Creative Tactic3D a sound card? If so you could drop that as it isn't needed and you could put that money toward upgrading your GPU to a Radeon 7870.
I'd also say switch out your SSD - or just drop it entirely and put that money toward your GPU. On a gaming build you want the best GPU you can afford and you don't want to skimp, compromise or purchase inferior parts if you can help it.
