Hello everyone! It's my first post here, and I'm picking my components for the first time. I've got a screenshot below of the components I've picked.

I do not need a PSU as I recently purchased a corsair tx 650W, running windows7 32b, don't need to buy a new HDD just yet either. The computer will be used mostly for gaming, and sometimes frapsing my ingame stuff and then posting some vids online
I do not intend to overclock it either, at least not just yet as I've not done it before so would rather run everything at stock.
So I would be grateful if you could share your wisdom and let me know if I've picked decent components, and if there is anything else I should be picking. I picked the cable tidy kit as I'm sure it'll be a wiry mess, but I heard with the Antec1200 if I wanna make good use of the hidden side on the right panel I should also buy cable extensions?
I'm also not sure if the motherboard is good enough - I don't intend to crossfire really, so it seemed suitable but I'm sure you guys know better.
