I find it funny he calls a raidmax "great solid power supply" they are one of the worst power supplies made. Uses a 3770k on a b75 motherboard(b75 cripples most overclocking features and is a budget board). the GTx 660 isnt a bad card but will by no means runs every game on ultra(unless you are running it at a really low res). The 3770k is good but not the fastest cpu on the planet. The only way he paid $1500 on parts is if he bought them exclusively from best buy on a high interest credit card. In other words I wouldnt buy it. You could build a better rig for $1200. Thanks for the good laugh though.
Those are the parts the user picked out. I know he mentioned 8 fans, but I don't think he meant 8 of the Xigmatek fans.
I'll briefly list issues I have with the build.
1) The CPU is overkill for gaming. He also states it's the fasted available. It isn't. That honour, IMHO, belongs to a SNE CPU like the 3970X.
2) The motherboard he used won't support over clocking.
3) The case is quite big, but the motherboard doesn't really allow for multi-GPU setups. (The second PCIe x16 slot is limited to Gen 2 @ 4x) Either change the motherboard to allow for multi-GPU, or get a smaller case. I have a big case (Antec DF-10) and I wish it were smaller. I'm not using all the room it has available.
4) I actually listed the 660TI, but he only includes the 660. The Asus 660 is $80 less than what he is offering. Note: I'm too lazy to change the build, even though it would take less time than it did to write point number 4.
5) Does he offer the warranties? Not every company will transfer warranties, so if something breaks in half a year, what then?
I'll attempt to explain all the parts I selected.
CPU: It's performance is about equal to a stock i5-3570k, but it's about $40 less.
Motherboard: It offers cross-fire or SLI, has high ratings, however, I can't speak about Asrock. As far as I know, they are a good brand.
Memory: Patriot makes perfectly decent RAM, and it's the best price, other than a single 8GB stick.
Storage: Great price, trust worthy brand, lots of space. Not nearly as fast as an SSD.
Video Card: The 7950 is a solid performer, and Sapphire is a good (IMHO) manufacturer.
WNA: Why not?
Case: Price, and looks.
PSU: No reason, other than being modular.
OS: I assume you don't want Windows 8, and also don't want Windows 7 Pro, and do want Windows.
Let me know what you think, and don't buy anything unless you can get at least one other person to say that my selected parts are worth buying. I'm a strong believer in second opinions.
