Question about 880 and 256 bit bus....

[Silent_Scone]

Nobody is sure that it will be on a 256 bit bus, if it is then id much rather go for a r9 290

Few sources have pretty much confirmed that part is true. Wait for the benchmarks!

Yes NVIDIA will be fully aware that if they release a rebrand of the 770 as speculated, AMD will slaughter it with Tonga, so I hope they will not be that naive to release a card that stuggles badly at higher resolutions.

We've all seen how the 290/X pulls away at higher resolutions so that's a warning they would gravely ignore.

I would take cod's recommended requirements with a pinch of salt. Ghosts recommended a 780 and I severly doubt that that was true.

It kinda does because of how badly optimized it is. I got 3.5GB VRAM usage during single player, it doesn't even look that great!

I dont think it would hinder you at 1400 but still better to wait and see imo. We still dont know how much vram it will come with yet. That could be a limiting factor for 4k more than the bus width

True but as I said its not for 4k and never will be. 1400p will be as high as it goes

I didn't state that there was a fabrication difference though. Maxwell is far more efficient than anything on the market today and using the 750 ti performance per watt as a guide, its not exactly going to be slow! Nvidia wouldn't release a new card that is barely an upgrade over the current stuff, especially when its in the next gen of cards branding, as they'd just open the door to AMD to release a monster of a card and plow their market share into the floor.

Nobody is saying that Maxwell's performance per watt is not great, but my point was that being stuck on 28nm would be there will be a ceiling of how far the GPU can push even with a new, more efficient architecture, and realistically, for the 880 it will be most likely be a card that offer similar level of performance (+ or - 10%) to GTX780/780Ti but with lower power consumption, rather than same power consumption offer much higher performance.

It is not a simple case of smacking more watts onto Maxwell and it would automatically making the graphic card faster...things such as the numbers of CUDA cores, transistors, ROPs that can actually fit onto GPU and the clock speed it can run at is far more relevant.
