Some changes/critique to that build since Fairy.Ghaleon beat me to it!
Unless you're going to do triple/quad GPU solution sometime down the line, I wouldn't bother with a 1k watt PSU.
Here's a great PSU (also Corsair!) that will definitely allow for a dual GPU solution, especially with the radeon7000 or geforce600 generation cards because they're very very power efficient.
CORSAIR Professional Series Gold AX750
Sandforce-based SSDs are generally not that stable. Look at OCZ Vertex3 and Vertex2, etc.
Anyway if you want to go with a Corsair SSD I would suggest this one:
Corsair Performance Pro 128GB
It uses a marvell controller and is faster as well, IIRC, but at the very least it's equal to or better than the Crucial M4 128GB.
Otherwise, it's down to one of these two:
Crucial M4 128GB
OCZ Vertex4 128GB
Note that the Vertex4 has a
5 year warranty which is reaaaaaaaaaaaaaally good for an SSD warranty (as good as Intel's SSD warranty, and Intel SSDs are the staple for reliability)
I don't see why anyone would use anything other than the de-facto standard of air cooling:
Coolermaster Hyper 212 EVO
While there's nothing inherently wrong with the Noctua NH-D14, it works really well as a cooler. The problem is that, with stock fans, it's not much better, if at all, than the hyper212. The Noctua NH-D14 is also over $50 more expensive. All you'd get is really nice aesthetics because, well, the Noctua NH-D14 looks really *** badass.
I love the case. I'm sure I've talked about it before in another thread. The only gripe I have is the USB3 is just a damned passthrough and Corsair hasn't updated it yet. The next best Corsair cases I'd get with proper front-panel USB3 would be:
Corsair Carbide 300R
Corsair Obsidian 550D
Or try some Antec cases:
Antec P280
Antec Three Hundred two
With the cost of mechanical hdd going down now, I'd pick up a 3TB drive for storage, doesn't cost too much more:
Seagate Barracuda ST3000DM001 3TB
I like that model line of the Seagates because they use 1TB platters. So this 3TB drive only has 3 platters as opposed to 4+ from other manufacturers. Less platters = less vibration/heat/power.
I always liked the look of the Asus boards with the "tuf armor" cover all over the pcb. Whether or not it serves a practical purpose, it looks bad ***.
As for video cards I'm partial to AMD/ATI but it's really hard for me to recommend anything from the red team this generation :(
Right now I think the nVidia GeForce GTX 670 is quite possibly the best card right now that's within a reasonable price ($400ish) so yeah...
Like the 7870 is a great card but it's not a $300 card. It's like a small step better than a GeForce 560 Ti which can be had for $200 or less depending on sales. The 7870 should be priced around $250 and the 7850 should be around the $200 mark. Tired of calling it AMD/ATI so just going to call it ATI now.
But of course there are reasons to get either models. Multi-monitor gaming with ATI vs single monitor 3d gaming with nVidia for one reason, etc.
Also ATI cards still work flawlessly with FFXI, assuming you even want to play FFXI with that computer!
Otherwise it's a pretty solid build. Could save money changing to Sandybridge i5 2500k instead of Ivybridge because it's really nothing new in Ivybridge aside from a die shrink and better Quicksync due to better Intel Graphics on the chip itself but I'd be nitpicking at that point.
Edit:
Arctic Cooling MX-4 is better and a LOT easier to work with than Arctic Silver 5. Actually almost any current high performance thermal interface material is better than AS5 at this point. That's not to say AS5 won't work though. I'm sure it will work just fine after a couple of weeks of heat cycling. Meanwhile, the other stuff works at 100% instantly and transfers heat better.
