Gigabyte Intros R9 270X OC 4GB with WindForce 3X Cooler
Gigabyte has announced its R9 270X OC 4 GB, which carries a WindForce 3X cooler.
It seems that many manufacturers are releasing R9 270X graphics cards with 4 GB of graphics memory rather than 2 GB, and Gigabyte is one more manufacturer to join the crowd. Its latest graphics card, the R9 270X OC, with codename GV-R927XOC-4GD, features something the competitors don't – a triple-fan cooler.
The card is built on a non-reference PCB design. The triple-fan cooler is known as the WindForce 3X cooler, and is also featured on various high-end graphics cards from Gigabyte. It is built with three fans, two aluminum fin stacks, as well as a number of heat pipes and a plastic shroud.
Gigabyte has clocked its R9 270X OC 4 GB at 1050 MHz base with a 1100 MHz GPU boost frequency. The memory on the card is clocked at an effective speed of 5.6 GHz.
There was no word on pricing or availability yet.

I bought a 2GB GTX760 and I'm very happy with it, it performs awesome on 1080p for all games I own, including Crysis 3, Battlefield 4 and Company of Heroes 2. But in two years? I'll have bought something new and sold my current 760 for the change... It's the only sensible thing to do.
YOU CANNOT FUTURE PROOF ON THE GRAPHICS DEPARTMENT!
to bad crossfire is completely useless for any triple monitor setup or 4k monitor requiring 4gb vram. May have a use for 1440p dx 11 games i guess.....
Consoles won't be pushing VRAM? When PS3/X360 consoles launched the usual game required 256 MB of VRAM. Now games to be run in 1080p, maxed out WITH FXAA require 1.5 GB or so. Not all games of course, still. Seing how proper PC games like Battlefield 3/4, Crysis 2 with MaldoHD and Metro games push VRAM easily with their amazing textures, (and that's now) think how will it be in a few years time.
You said PCs built now will be underpowered? If you bought a new PC at the end of 2006, 3-4 GB of ram, and 8800 GTX 512-1GB (SLI or not) and an Intel Q6600 you could play ALL games today (sans the 2-3 or so DX11 only games) no problem, even in 1080, on medium-high.
If you would've bought something with 256 MB, by the end of 2007 you were already out of luck. Even 512 MB by the end of 2010 was pushing it.
See where I'm going?
Better anti-aliasing methods, tessellation, and paged streaming from the System RAM are all reasons why VRAM usage could be reduced.
Mantle in particular, once optimized in several years, can get away with a FRACTION of the video memory for a similar experience to now.
The new consoles will influence things of course, but keep in mind a game might have access to a SHARED 5GB (say 2GB of "VRAM" and 3GB of "SYSRAM") which on PC can easily be done already with a 2GB card and 8GB of System RAM.
That said if things really do go to a unified memory architecture, then the discussion is moot. Id rather just have one large pool of ram for the system; rather then the system and video ram split we have now.
Things are just straight up inefficient when you have to copy textures from system ram to video ram, use them, then copy them back. Or vice versa.
If you compare a pair of 4GB 270Xs in crossfire to one 290, they are exactly the same at every spec but clockspeed (should be easy enough to OC a 3rd party cooled 290 to 270X clocks). On top of that, a 290 would not have losses from crossfire, giving it greater performance than the 270Xs. An OC'd and properly cooled 290X would probably sit even higher. The only way this card makes sense is if you want to crossfire three of them, one wouldn't be able to use all that VRAM, and two or four of them would be better replaced with one or two Hawaii cards.
I know you will probably say that "then, you're better off just buying the 290", but many people prefer to (or are only able to) buy 1 cheaper card now, and upgrade via crossfire in the future.
For all that group, it's a lot better to buy a 4gb cheaper card, if available, as it opens you up to better crossfire in a future...
And that stuff about crossfire broken at higher res/multiple screens, that's only temporal till they give us newer drivers.
Hopefully sooner than later.
