Gigabyte Reveals GTX 770 WindForce 3X OC, Has 4GB VRAM

Gigabyte has announced a new version of its GeForce GTX 770 card, this one packing a meatier cooler and more memory. The GTX 770 WindForce 3X OC is a card that is built using a custom PCB, carrying the WindForce 3X cooler, having higher factory clock speeds, and a couple of extra gigabytes of graphics memory.

The card's WindForce 3X cooler is built with six copper heat pipes, some big aluminum fin stacks, and three 80 mm fans. This cooler can generate up to 450 W of cooling power. Of course, with such cooling power the manufacturer cannot get away with giving us a card with factory clocks. As such, the card is clocked at 1137 MHz base and 1189 MHz boost speeds. This makes the boost clock over 100 MHz higher than the reference specification.

Gigabyte's GTX 770 WindForce 3X OC also carries 4 GB of GDDR5 memory that runs over a 256-bit memory bus at an effective speed of 7.0 GHz.

The card should already be available through retail channels for an MSRP of around $499.99.

    if you dont have a piece of silicon that isnt powerful enough to drive the extra vram you slapped on, what is the use? just like how there are gt 640s with 4gb of vram

    11.5" long. Won't fit in my case. My EVGA 770 is 10.5" and it fits, but only with some effort.
