Report: Sapphire Building 8GB Radeon R9 290X 'Toxic' Card
It looks like Sapphire is working on a 'Toxic' R9 290X graphics card with double the GDDR5 memory.
A report from KitGuru tells us that Sapphire is building a new and improved R9 290X graphics card – one with a rather impressive spec sheet. The card will be known as the R9 290X Toxic Edition.
The card seems to be based off of the original Tri-X R9 290X graphics card, though they do carry a number of differences.
The biggest difference between this card and other R9 290X cards in general is the 8 GB of graphics memory, rather than the reference 4 GB solutions.

So far, there has been no information on what the card's clock speeds would be, but given that this is a 'Toxic' branded product, it's safe to assume that the factory overclock will be at least respectable, if not better.
Of course, there is also no word yet on pricing or availability. That said, it will be a limited edition card, meaning that prices are likely to be a little higher than usual.

Skyrim modded to heck and back, sure it was pretty, but it also brought my friend's Titan's memory usage pushing 6G on that card. He runs a tons of mods though. Still played great obviously but tracking memory usage, it got fat fast. Those are massive textures, etc being loaded also pushing visuals and not performance.
That's just one example that comes to mind.
OMG, I just remembered... He's running 1600, not 1080 so that is roughly twice the pixel count. Sorry about that confusion on my part. (I'll fix the post.. ) I always forget that. (I want a 1440 as I prefer wider over taller, but $... And I do most of the testing accept that one). One gotcha is probably some of these mods aren't as optimized as they could be, wasting a ton of room that might not be necessary. Still they do get pretty but also require resources to execute especially when combined with others and others and... You can still load up the same extreme res texture packs though and give your system a grind. I've easily peaked out my 690 in testing (2G per).
Still, if 3x or the newer 4K come to the mainstream (which are ALREADY available), then this becomes a far easier and more serious 'need' for those niche users real fast.
8K GAMING HERE WE COME, right up some code nvidea we need 8k enabled support, oh my bad lol. amd.
