Any feedback on this gaming PC configuration?

Hello all, I'm looking to build a gaming PC on this site for $1600 to $1700 max. Here's what I've developed with some help from some friends of mine, and my own input:

Specifications: 
Chassis Model: Special Deal Hot Seller - Cooler Master CM 690 II Advanced 
Processor: AMD Phenom II X4 965 (3.4GHz) (Quad Core) (Black Edition) (8 MB Cache) AM3 Socket 
Motherboard: Gigabyte GA-890XA-UD3 (AMD 790X Chipset) (SATA3 and USB 3.0) (Socket AM3)
System Memory: 4GB DDR3 1600MHz Corsair Dominator DHX (High-Performance) 
Power Supply: 750W Digital Storm Certified (Dual SLI Compatible) (Silent Edition Recommended)  
Hard Drive Set 1: 1x (1TB Hitachi/Seagate (7200 RPM) (32MB Cache) 
Optical Drive 1: DVD-R/RW/CD-R/RW (DVD Writer 24x / CD-Writer 48x)
Video Card: 2x SLI Dual (NVIDIA GeForce GTX 460 768MB (Includes PhysX Technology) 
Sound Card: Integrated Motherboard Audio
Extreme Cooling: AIR: Stage 1: High Performance Cooler (Compatible With ONLY i5/AMD Processors) 
Chassis Airflow: Standard Factory Chassis Fans
Internal Lighting: Internal Chassis Lighting System (Blue) 
Boost Processor: FREE: Stage 1: Overclock the processor between 3.3GHz to 3.9GHz (Cooling Upgrade Recommended)
Boost Video Card: FREE: Yes, Overclock the video card(s) as much as possible with complete stability 
Windows OS: Microsoft Windows 7 Home Premium (64-Bit Edition)
Display: !PROMO BUNDLE: Acer 22 inch LCD + Logitech (Keyboard + Mouse) + Logitech Speakers 

So I have a few questions that I'd like to be answered.
Is the cooling system enough? If not, what should it be?
Is rolling with 2x SLI 460s a good decision over, say, 1x 470? I'm pretty sure SLI 2x 460s are better.
I'm also pretty sure that 1x Radeon 5970 would be better than my current Dual SLI 460s, if I'm right, I'd like to see if I can 
play with this configuration to make a 5970 possible.
If I got a 5970, I think it would also be easier to upgrade my GPUs in the future, since crossfire seems to be 
much more versatile than SLI, from what I've seen.
Here's an important one: Is my processor overkill? Remember, I'm looking to build a good gaming PC, that can run
most games at good framerates at max settings for years to come.
Any other feedback would be much appreciated, thanks!

Why shove a SSD into a build under $2k to start with? In my opinion, you're wasting the 8% of his budget that you used to stick it in there. SSD's are too new to be worth sticking into builds until at least $2k.

If you drop the SSD and leave everything else the same, you can bump up to a 470. I'd recommend doing that because gaming's bottleneck is graphical power, not hard drive speed. In other words, you want the best graphics you can fit in your budget.

Thank you all very much for the feedback thus far. Your build suggestion, ablahblah, was pretty solid for my purposes for the most part; besides for the SSD and processor(which I will explain later). I agree with Runes on his supported opinion that on a gaming rig, the GPU takes priority over getting an SSD on this kind of budget.

And no, 2x 460's is not "better" for a variety of reasons.

I trust this, since you probably know more about SLI than I, however, out of curiosity, would you care to explain why? I've heard several different arguments for, and against SLI on this rig.

As far as my processor is concerned, I'm pretty sure I'm just going to stick with the AMD Phenom 965 quad core. The processor you suggested, ablahblah, wasn't compatible with a motherboard that supported USB 3.0. I know that the intel supports HT and is better, but honestly, I think the AMD will be fine, I don't plan to be doing anything significant outside of gaming right now that would make the intel you suggested impact performance a lot. If I get into graphic design, or something, I imagine it'd be fairly easy to upgrade the processor to a 1090T. I will be overclocking the 965 anyway. I am taking your advice and not overclocking the video card though.

I'm confident with this build (which is basically the first one I posted except it has a 470 instead of the dual 460s, the cooler, and case that ablahblah suggested.) and I plan to be making a purchase very soon.

Digital Storm has been great, good savings, good community, and a very friendly interface with awesome perks that provide a sense of caring about what they do, definitely satisfied with my experience here.
