Is the 7970/280X now the "go to" 1080P GPU for those sensitive to frame delivery?

Quite a turn around, looking forward to 290 and 290x crossfire data.

I believe that is single card. AMD basically fixed the issues with single card and single screen resolution CF frametimes - they are on par with NV in this respect, sometimes better. Actually the 280X *does* have impressive frametimes, mostly beating the GTX 770 in that respect.

That said, the remaining question mark is eyefinity CF - eyefinity CF has had issues for some time now, and still is not fixed. GTX 770 SLI will still be far better in surround than would 280X CF eyefinity. Surround is a niche, sure, but I would say multi GPU frametimes are more important for these folks than any other, as CF/SLI are mostly necessary for surround resolutions.

That's why I'm interested in seeing how the 290 and 290x do in reviews in terms of crossfire frame delivery. I might switch to a 1440P screen for gaming but I'm considering sticking with 1080P + Radeon 7950 and making the gaming resolution switch in a year when 20nm GPUs hopefully show up.

That's assuming 20nm Nvidia and AMD cards push GK110 and Radeon 290 performance down into the $300 range. If it happens that way I'll be looking at SLI or Crossfire.

Depends quite a lot on the game. The frame times and variance of them is by and large now dominated by the performance and that seems heavily dependent on optimisation. If its an AMD developed title it typically does better on AMD hardware and an NVidia supported title typically does better in frame times on the games they supported. The performance difference between these two cards is quite small overall. The 770 is on average (according to ABT and gamegpu.ru) faster on a wider range of games but its also more expensive.

If FCAT and frame times has proved anything its that there is a point where it does matter below which it probably doesn't. Despite the problems AMD had at the end of 2012 on single cards that issue does seem to be fixed now. I don't know if its cleared up for good because they never came back and said they had fixed the garbage collector in their driver which they claimed was part of the problem, that work and problem was overtaken with the FCAT and frame pacing issues. But I haven't seen an editorial or anyone complaining about this issue in these forums for quite a while now.

This is test where the 770 averaged 33FPS, which is 33.3msec per frame on average. You'd expect that with the cutoff right at the average frame time that a number of frames would be over the average by some amount no matter how good the frame pacing was. Without knowing how many frames were above the average and by how much, you can't tell if there were quite a few frames +/- 5% of the average or big jumps in a small number of frames.

Looking at the latencies by percentile on the page you linked to, it seems that maybe the 770 is a small bit worse in the slowest few percent of frame times. But in general I don't see anything questionable in the results.

There is a point where frame time variance doesn't matter anymore. That point is when AMD card have better frame pacing than nvidia card. /joke /half-serious

Was there a problem with single card solution in the past?

It was with one of the drivers and a few games for like less than a month. Ofcourse it was then turned into ALL AMD cards are worse in ALL games than Nvidia cards ALL the time. even though the the same site that came accross it didn't have the issue a few weeks earlier with the same games.
