I have been fortunate enough to use the 670FTW in single, dual, and triple card setups (with and without dedicated PhysX), and a 3-way SLI setup with a decent overclock (especially on the memory) results in constant 60fps+ with everything set on maximum (except for MSAA, which anything beyond 2-4x does nnot give any benefit on the QHD/WQHD panels IMO, but costs a lot of performance), playing on a Dell U3011 both alone and flanked with 2x 1600x1200 screens in portrait(4960x1600). It wwas only the last configuration where I noticed any slowdowns in the SLI setups, but for themmost part thepperformance was surprisingly good.
Also, overclocking the 670FTW memory from 6008mhz to about 7200mhz resulted in a substantial performance increase, around maybe 15-20pct on average with the higher resolution displays.
I haverrecently had a chance to play with the Dell 21:9 panel, and I am still undecided... Here are my thoughts on it:
- Very wide display gives you a real sense of immersion
- You have to sit as close as you would a 23-24" 1080p panel as it's not very tall
- In many ways it feels like Surround gaming "lite" in that it gives you a middle-ground between a single monitor and three
- No bezel for the width it gives is an important factor to me as I get distracted by any bezels
- Films in their native 21:9 aspect ratio look better than on anything else I've seen, and the monitor scales them to fit the resolution incredibly well
- Would be an absolutely perfect center panel in a middle-ground surround setup (middle ground cost-wise)
- No portrait mode irks me
- Excellent color, contrast, and off-angle viewing (not as good as the U2711's color, but better than the Achieva and Catleap I've seen)
- Input lag isn't great, but it isn't terrible either... Never felt like I was "behind" by a few frames
Sitting about 2-2.5ft away, everything feels about perfect. Your horizontal FOV is mostly encompassed, and the loss of some vertical pixels is quickly forgotten once you start actually using the monitor and stop focusing on it.
The width of the monitor is ideal if you have stereo/2.1ch speakers as placing FR/FL about 6" to either side of the edges and with about a 10-15deg toe-in results in fantastic imaging, and gives you a very good phantom center channel.
The height of the panel makes it absolutely perfect to use with a pair of U2312HM displays, one per side, for Surround.
HHowever it's one of those love it or hate it things, and I would definitely adviseyyou to try one out.
Oh, performance was about exactly between the 2560x1600 and a single 1080p display, with a single card being plenty capable but 2 providing a locked-in 60fps!
