Is recording games very CPU or RAM intensive? I don't know, honestly, so if they are then ignore the following:
- Drop down to 8GB RAM
- Drop down to the i5 3570k... cheaper and performs just as well for gaming
Don't get a 3TB internal hard drive, I've heard of a lot of problems. I'd probably just get a 2TB or even two if you really need the space.
Sorry, I meant SLI, since you have an Nvidia card. With a 670 you shouldn't need to for awhile, but it's nice to have enough wattage to know that you can in 2 or 3 years when you want the extra graphics power. So I would say that for now, one 670 is plenty powerful, but leave room in your system for another one in a year or two.
Ok Now I have two 2TB hard drives and I switched to the gigabyte 670, I think I need the ram I picked and I've heard that i7 is better for editing too, which I will do a lot of. Anything else you think I would need?
A case might be helpful. Maybe. Take a look into the NZXT Phantom, Corsair Carbide series, Corsair Obsidian series, Silverstone cases, Cooler Master HAF series, the Fractal Define, and BitFenix cases. Find a few that fit your price range, personal tastes, and has the features you'll want. Look around for some reviews on them, too, those are always much more enlightening than a feature list on Newegg. I'll help you look when I get a bit more time later on.
Edit: On the more expensive-ish side, you could get this Corsair Carbide 500R (White) for $140. There's the NZXT Phantom 001 I mentioned for $120 (it comes in lots of other colors, too), or if you'd like something more affordable you could get the Cooler Master HAF912 for $60, and then load it up with some real nice third-party case fans (Scythe, Noctua, Corsair, BitFenix, etc).
Idle noise levels are outstanding, actually the card is the quietest GTX 670 we tested so far in idle. Under load the fan ramps up a bit but ends up being much quieter than the NVIDIA reference design. It is barely audible under load, but we've tested other cards like the ASUS DC II that is even quieter.
