PC Build Please Help ? Following Specs ?

Unless you know you need 12GB, you should stick with 6GB. Cooler, less power, faster. Having CL7 or CL8 RAM could help any overclocking you wanted to do, if the price is about the same.

You could downsize the case to a HAF912 and drop the PSU to a good 650W PSU unless you plan to add a second 5870.

Reviews show the Venemous X to be a decent cooler, but not better than a bunch of cheaper coolers with longer track records.

You won't need 12GB RAM; I would take that money and throw it into another graphics card in CrossFire (or SLI if you end up going Nvidia).

Like dnd says, you can drop the PSU if you don't think you'll get a second video card.

You could save a little money by going with a smaller SSD. At the moment they're really only good for your OS and a few programs (your video editing program, for example), but they shouldn't really be used for every day storage (that's what the 2TB is for). I have a 64GB SSD (got it on sale) and I've filled only half of it...
