I oc my cpu and i am thinking of the 3 fan windforce 7950 and then xfireing in the future but the gtx 670 and 680 prices are decreasing and even my crappy 700w can support two gtx 660s non ti the xfx 7970 is great too. No i dont care about noise and i am thinking of bf3 gta iv and v srtt etc
The MSI PE 670 is awesome MSI Power Edition Architecture Boosts Overclocking Potential by 22.5%
The MSI GTX 670 Power Edition graphics card is based on the MSI Power Edition architecture: Afterburner's Triple Overvoltage allows the GPU, Memory and PLL(Aux) voltages to be adjusted . The Enhanced PWM design provides 25% more current than the reference design to ensure high stability during overclocking.
Twin Frozr IV: 20°C Cooler and 11.7dB Quieter than Reference Board
The MSI GTX 670 Power Edition is equipped with MSI's latest Twin Frozr IV Thermal Design. MSI's exclusive Dust Removal technology automatically reverses the fans at startup to prevent dust build-up dust and optimize the cooling module's ability to dissipate heat.
Patented Propeller Blade technology provides 20% more air flow over conventional fans and increases the effective cooling area. When combined with dual 8 cm temperature-controlled fans, SuperPipe technology, and a nickel-plated copper base, temperatures are effectively reduced by up to 20°C and noise by 11.7dB!
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 $30 price premium for their card, which doesn't look unreasonable, given the improved cooling and higher clocks.
Sapphire's HD 7950 Vapor-X comes with a large dual-fan cooler that uses the company's famous vapor-chamber technology. On the Vapor-X you will also find a "Lethal Boost" button which switches to a second BIOS with higher clock speeds. With this BIOS, clocks are increased to 950 MHz GPU and 1250 MHz memory.
With NVIDIA’s GTX 660 Ti being released, many believed its low price of $299 and the subsequent introduction of AMD’s HD 7950 Boost would eventually encroach into the GTX 670’s territory. In some instances, this may have happened but with custom, pre overclocked products like MSI’s Power Edition OC, the GTX 670 has remained extremely competitive. This card is able to provide class-leading performance at every resolution without costing a fortune.
The GTX 670 Power Edition OC bridges gap between two highly regarded competitors: the ASUS GTX 670 DirectCU II TOP and Gigbayte’s GTX 670 WindForce OC.. With an excellent heatsink design and upgraded components the Power Edition shares many of the same characteristics as its competitors but a price of just $409 puts it well ahead from a value standpoint even though its performance remains a bare half step between ASUS’ TOP-branded beast. MSI’s card also exhibited the lowest acoustical footprint we’ve seen from a GTX 670.
Aside from whisper quiet fans and low temperatures the MSI GTX 670 Power Edition OC’s primary selling point will be its in-game performance. With framerates easily matching or surpassing NVIDIA’s $499 GTX 680, we really can’t think of a better card for a wide variety of in-game situations. In many ways it is a actually a perfect alternative to NVIDIA’s flagship card since MSI’s Triple Overvoltage feature allows for some impressive overclocks with only a moderate amount of voltage. The GTX 680 will tend to pull ahead at higher detail settings but more often than not, the framerate difference between these two cards will never be noticeable to gamers.
For those of you wondering, AMD’s loud, power hungry HD 7950 Boost never really came close to matching the Power Edition’s performance or overall value. There were a few very rare instances where the HD 7950’s higher memory bandwidth allowed it to pull ever so slightly ahead but for the most part, the PE was miles ahead and would remain so even if compared against a pre-overclocked Boost edition.
MSI’s GTX 670 Power Edition OC is one hell of a graphics card. It combines near-silent acoustics and excellent overclocking abilities with performance that hits far above what its $409 price would initially indicate. Unless ASUS, Gigabyte and nearly every other NVIDIA board partner lower their prices, the Power Edition OC will remain one of the best bang for buck purchases in the current GPU market.
