I do recomend the 3rd eye bit, as I like to be able to keep an eye on my temps when playing games, on the uguru clock. And you can go to your pre set over clocks with it during a game (but isn't probally a good idea) but i like to be able to put it back to default if I didn't like the overclock during a game.
If you like that case, get that psu, and put it in the bin and buy a new one, something like Antec, but with more than 330watts, which was my mistake
You might as well make use of the dual channel memory so go with the 2X256.
If you are going to be doing alot of overclocking get the faster ram, as it would run at pc3200 (the fastest AMD's support right now) and it will enable you to have a higher overclock.
also have a look at this website: http://www.overclockers.co.uk/acatalog/
edit: I believe venice cores are coming out very soon, you may want to wait for them.
