well, in my opinion first of all, nvidia 8000GT series and ati HD4000 series have no sense to play GTAIV + ENB.
I do not checked 660ti and 7970, but yes 460 and 6870 by myself. oh yes, and I said on a phenom 945, not 955
I play at 1920x1080 with all effects at max too, only view distance is not up to the max because overcharge the CPU, and a friend with a i7 2700 tell me he can NOT use 100/100 of view distance, but not tested by myself...
and shadows at high if I play on 220.127.116.11 because this render have much more quality than old patches and overcharge my GPU (and very high on old patches) but in bouth I have better performance with 6870 than 460.
I tried the main ENB: DKT70, DP3, L3EVO, ICE, and even your own ENB mix and the mostly of gta4-mods from last 3 years.
ps: you said your 2600k and gtx580 wasn't cheap when you bought it? well, I guess you are a lucky guy with a very good job, good for you, I have to settle for a more modest budget, but believe me I play >35 fps @ 1080p and I'm very happy
It's a FACT that GTA IV runs really bad on AMD Cards, Nvidia have a MUCH better performance. About Processor i don't really know... that shouldn't be the problem.
FPS always depend on Ingame Setting and the ENB you use, I have 30-40fps with my current ENB and gtx580/2600k. So you can't tell in general about it.
Try to inform yourself before you write something you don't know about
I really want see that "MUCH better performance"
I have a 6870 and my brother a gtx460, believe me, I know what I'm talking about, and you don't need a i7 2600k + gtx580 to play gtaiv with ENB mate, but good for you, you have very very cheap and powerful PC, congrats
1. Are there some disadvantages or bader graphic compared to a ENB mod running on 18.104.22.168? I've read that ENB only has full power on 22.214.171.124.
The current ENBSeries is in BETA (v0.082b) and icenhancer is this beta ENB too (only change the name), and with newest patch SSAO and skylighting not work. If someday Boris Vorontsov finish of ENB development for GTAIV will be fixed, but at the moment is what we have
2. Is the sunrise/sunset like a orange sunrise or is it the ugly one like in Icenhancer?
I'm not sure, but in the screens looks like "dreamy" sunrise, try
3. Is there the red sky bug?
Yes, due to skylighting issue, but in this forum "china green elvis" has posted a FIX for red sky bug and works like a charm, but I don't know how works in that ENB you mention, you can try
4. Is there already a blood mod included or can I use a blood mod?
Yes, but you can use whatever you want, just replace the files
5. Should I first install this mod and after that other mods or this mod at last?
PSU 700w is excesive, is better a 500-600w but a quality and efficient psu than to much wattios but poor efficient/quality.
about cpu-gpu I have to agree, very powerful cpu but a poor gpu, you don't need that super cpu, his performance doesn't worth for the overprice, and that gpu really sucks, go to a HD6950 or HD7850 or higher.
