Yeah, but why wait for NV to get it's act together? I just don't get how people make excuses for Nvidia all the time (not saying that you are). Just use AMD, they have the best products out, and IMO have since the 4800 series when I dumped Nvidia due to driver issues and no audio over HDMI (at the time). I have all the money I could want, and I wouldn't spend it on a 580, I'd get the 6970 which is a guaranteed ace in the hole.
You can call me whatever you want, seeing as how when I first joined the forums I was accused of being an NV fanboy, then an AMD fanboy, now an NV fanboy again apparently. Whatever, I think I am one of the more impartial and consistent people around here.
I don't think the HDMI thing is a big deal because who actually uses a GTX580 for HTPC usage, anyway? And if it's not going into an HTPC then you have other ways to get that audio.
The bigger issue imho is lack of single-GPU Surround. It was the biggest reason why I switched my order from a GTX460 to a HD6850 after my initial GTX4604-768MB order arrived defective (damaged PCB).
NV's Surround software also sucks compared to AMD's hotkey system where it's easy as pie to switch modes. This is a big deal to me because of all the switching I do:
a) single-monitor centered (side panels disabled)
b) tri-monitor Extended Desktop centered
c) tri-monitor Eyefinity
d) tri-monitor Eyefinity with bezel correction
I understand that there are a few hacks like Zotac's 460 that does triple-monitors up to 1600x1200 but that's just a hack. Hopefully Kepler will ship with full single-GPU Surround support, full HDMI 1.4 support, and Surround software with hotkey profiles.
