I Take a look on the best ITX Sizes Graphic Card today, ASUS GTX670 DirectCU Mini OC 2GB Edition Graphic Card , Let’s check out the Graphic.
• The small form factor GeForce® GTX 670 graphics card for ITX/mATX gaming PCs
• DirectCU with vapor chamber offers 20%(7.5ºC) cooler and 3X quieter performance
• New and advanced CoolTech Fan drives wider airflow to keep critical components cool
• Direct Power ensures stable performance with 56% less impedance and a 17% cooler PCB
• Super Alloy Power components increase product longevity by up to 2.5X compared to reference
• GPU Tweak helps you modify clock speeds, voltages, fan performance and more via an intuitive interface
Driver DVD, a Manual and a power Cable is what I have Found inside the Box.
The Card: Top View
ASUS GTX670 DirectCU Mini OC 2GB is originally clocked at Base Clock of 928MHz and Boost Clock of 1006MHz from Nvidia Specifications but ASUS overclocked it to Base Clock of 915MHz and Boost Clock of 980MHz, the DirectCU Mini stands for (Direct Copper) Heatsink , which means the Heatsink is directly attached to the GPU Die, what’s new on this Graphic card is the Version Name “Mini” which the Graphic Card gets its self a Cooling Solution a unique design custom vapor chamber technology and the new and advanced 360-degree CoolTech fan that gives 20% Cooler and 3X Quieter Operation from the stock reference GTX670 Graphic Card.
Back Side View
The Card Doesn’t have Black plate, but it have Direct Power on the rear side of the card , This provides high quality and reliable power delivery to the GPU, whether for gaming or overclocking. In addition, superior efficiency reduces PCB temperatures by 17%.
You can see here the heat sink does not have any heat pipe coming out of it, this is Good Compact Style VGA Card to have inside ITX Chassis, in addition that this card takes only 2 PCI Slots on the Motherboard, It require only PCI-e 8 Pins power cable in order to run the card.
The card can do up to Quad SLI
The card have 2x DVI Ports, 1x HDMI and 1x Display port.
Under the Hood:
Removing the heatsink from the PCB is easy to do, the heatsink is in one piece and it cools the GPU, RAM and the Mosfets on the PCB.
The Core is nVIDIA GK104 Kepler Architecture it’s a 28nm GPU Size originally clocked at a speed of 915Mhz in Base and 980MHz in Boost. But in this sample the clocks are at 1006Mhz in Boost and 928MHz in Base clocks.
A closer look on the Memory chipset which is shows that’s it’s by ‘Hynix’, and carry the model number H5GQ2H24AFR-ROC. They are specified to run at 1500 MHz (6000 MHz GDDR5 effective) 1.6v, ASUS ran the Memory on this Card to 6008 MHz which is almost the same speed
On a view of Mosfets , Capacitors and Choke Fertte , thos components comes under category called “ Super Alloy Power “ which ASUS Calls them , basically This provides high quality and reliable power delivery to the GPU, whether for gaming or overclocking. In addition, superior efficiency reduces PCB temperatures by 17%.

Overclocking & Temperatures :
using ASUS GPU Tweak to overclock the card to get the GPU Boost Core Clock up to 1175 MHz Stable and Memory Speed at 7008 MHz by adjusting the power Limit to 116% in GPU Tweak and no Voltage Adjustment took little time to figure out the stable clocks, after that I used Furmark for 15 min stress bench to make sure that the clock speeds are quite stable while the Card on Auto Fan speed
Temperatures on Idle were 27c using Auto Fan control and 72c on load, since the voltage is not changed but speed is, therefore the temperatures were the same on idle and on load. Adjusting the voltage to higher is actually useless in this condition because I did not see any overclocking improvement beyond 1175 MHz on Core clock.
will go for GTX670 , because its overclocking performance outperform GTX760 , and in this review sample of GTX670 , its an ITX Sized Card that can fit into a ITX Casing so you can have Ultimate ITX Gaming Setup with it
