MSI N770 Lightning.. The Lightning Continues...

Question

From MSI N680GTX Lightning to the R7970 Lightning, now comes the new N770 Lightning. 
First of all let’s talk about the GTX 770 GPU Chip. It has the same GK104 graphics processor as the GTX 680 have but cranked up. Reference core and boost clocks have been raised to 1046MHz/1085Mhz and the memory speed to 7GT/s.  Aside from this, the GTX 770 GPU Boost has been upgraded to version 2.0, allowing Higher Clocks to punch in more often.
Comparing: GTX 770 vs GTX 680
Stream Processor:1536 - 1536
Texture Units:128 - 128
ROPs   :32 - 32
Core Clock:1046Mhz - 1006MHz
Boost Clock:1085Mhz - 1058MHz
Memory Clock: 7Ghz GDDR5 - 6Ghz GDDR5
Memory Bus Width: 256 Bit - 256 Bit
TDP:230W - 195W
Transistor Count: 3.5B - 3.5B
Mftg. Process: 28nm - 28nm
Now with the N770 Lightning, the video card has been factory overclocked to a core speed of 1150 Mhz (ref. 1046) and a boost clock of 1202 Mhz (ref. 1085) while the memory clock has been kept on a standard speed of 7010 Mhz. The GTX 770 Lightning will also use MSI’s GPU Reactor providing higher power levels and cleaner signals for the GPU. Other components that MSI have integrated into the card are the Military Class IV, voltage check points and 8+8pin PCIE Power connector thus making the video card break limits in the world of overclocking.
Here are the things you will find upon flipping the front cover of the box…
For the accessories…
•Certificate of Quality & Stability
•Quick User’s Guide
•Driver Utility Disc
•SLI Bridge Connector
•V-Check Point Connectors  (connecting this with your digital multi-meter will show the actual voltages of certain components of the video card like the GPU)
•2x 6 Pin to 8 Pin Power Connectors
•DVI to VGA Adapter
With the Lightning’s TwinFrozr 4 cooler, it promises to bring the video card temps below 60c and at the same time being quiet. It also boast the 2x 10cm Propeller Blade Fan technology which provides higher air volume to the card for faster heat dissipation. Dust Removal technology is also been implemented now in the Lightning series of video cards as it automatically cleans your video card.
Two SLI bridges on top of the N770 Lightning and to clarify things up, it is only intended for a Tri-SLI configuration.
Below are three SuperPipes with one being on top which also helps cooling the GPU chip. You can also see at the bottom part of the video card the Golden SSC Military Class IV Components.. These components are no ordinary; they can withstand extreme conditions, run with stability and power efficiency and provides longer lifespan to the video card.
Checking the back side of the card, back-plate is installed thus making it cooler and to avoid bending the video card. The blue circle thing you see there is the GPU-Reactor – an additional PCB connected at the back of the video card which also lights up when powered up.
Video Outputs:
•Dual-link DVI-I x 1
•Dual-link DVI-D x 1
•DisplayPort x 1 (version 1.2)
•HDMI x 1 (version 1.4a)
My Test System:
•Processor: Intel i7 3770K
•Motherboard: MSI Z77 MPower
•Memory: G. Skill Pi Black 2x2GB 2200Mhz
•SSD: Kingston HyperX 3k 90GB
•PSU: Antec TPQ 1200
First set of benchmarks are all on Stock Speed.
1. 3dMark06 29765
2. 3dMark Vantage P34525
3. 3dMark11 P10759
4. Heaven DX11 X 2341.411
2nd Set of benchmarks, all were overclocked. From the Processor, Memory and as well as the Video Card. You can also see that the video card would perform better on an overclocked Processor.
1. 3dMark06 38407
2. 3dmark Vantage P39691
3. 3dmark11 P12356
4. Heaven DX11 X 2477.77
That would be it 

Answer 1

Hello,
About PSU: 450W is not enough for either of them. For 760 or above it is recommended to have 600W (as the minimum) power supply.
Both cards has similar cooling, but I would prefer lightning edition (hey, it's 770 not 760 which is little bit lower in performance). However if you also look for the design to fit your case, then that's up to you. Obviously if the card will run hot, most likely you will have to reapply thermal paste (very common in case of GPUs).
Your shop is very limited, but why not use this search, just pick your country Already selected for N770 lightning
