#1 I would be all over that Asus TOP for its high factory overclock, cool temps, and really, really quiet fans.heavily modified PCB, with an efficient VRM design to produce low temperatures, improved voltage regulation circuitry, much better ChiL controller , specially binned chip and voltage control and monitoring support that you won't find on most other non-reference cards. It looks aggressive to me and indeed is monster let's keep it on the real. TechPoweUp gives the 670 TOP an 10.0 rating, the only 10.0 rating ever
Asus 670 TOP - 10.0 rating

Yes, you've seen correctly, the ASUS GeForce GTX 670 Direct CU II TOP is the first graphics card ever that I gave a perfect ten score. The stock GeForce GTX 670 provides already great performance, but ASUS has topped that by boosting it with a large overclock out of the box which catapults it beyond GTX 680 performance levels. Averaged over all our testing we see the card 1% faster than GTX 680 and 8% faster than GTX 670. The card does so without massive power consumption increase thanks to an efficient VRM design and low temperatures. ASUS has done away with NVIDIA's cheap voltage regulation circuitry and put a much better CHiL controller on the card, which also supports voltage control and monitoring.
The ASUS DC II cooler is a revelation on the GTX 670, it provides incredibly low noise levels. In both idle and load the card emits almost no noise, it is actually quieter under full load than most other cards on the market are at idle. Not only noise is low but temperatures are great, too. With only 74°C under load the card is cooler than most other GTX 670 cards tested today.
Manual overclocking works well too, especially memory, which is not overclocked out of the box, performs exceedingly well. We see well over 100 MHz extra memory overclocking potential compared to the NVIDIA reference design, thanks to the revamped PCB design. In the end the card reaches 1890 MHz memory, which is just 5 MHz shy of the highest memory clock ever recorded in a TPU review.
Overall the ASUS GTX 670 Direct CU II is the best card I ever tested. I simply can't find anything wrong with it. ASUS has sucessfully addressed all the shortcomings of NVIDIA's reference design, yet asks only a moderate $20 price premium for their card. This means that you can get faster than GTX 680 performance at $420. And the card manages all that with a dual slot cooler, that just screams "put me in SLI".
#2 MSI's GTX 670 Power Edition uses the famous Twin Frozr IV cooler from the MSI Lightning and comes with a large clock speed boost out of the box, making its default clock speed even higher than GTX 680 stock clocks. MSI is asking a $389.99 it's actually $369.99 AMIR price for their card, which doesn't look unreasonable, given the improved cooling and higher clocks.
ASUS GTX 670 TOP = Silent.
MSI GTX 670 PE = Better Overclocking.

Pick which you care more about. Nothing is Perfect between those 2 card. If you care more about silent, I would choose ASUS, but if you care more about Overclocking. Both are Excellent card.
