..
thanx
1. awesome. I forgot to ask where you will be buying from though? I'm in Canada so I could go on and convert funds then base my prices on stores here, but that might not entirely reflect prices where you are.
2. Of course the i7 is a better performing CPU. But in most cases, the performance gain is not worth the price. Or not even needed or noticed.
3. Awesome. But you forgot to mention your monitor resolution. Size of the monitor does not make a difference. The number of pixels the GPU has to render makes a difference. Your samsung is either 1280x720, 1366x768 or 1920x1080. Alternately, the first two resolutions can be labelled at "720p" and the third can be labelled at "1080p".
"All Games with max quality". That is a high request. The game Crysis, for example, still cannot be rendered at 1920x1080 with max settings and 16x AA enabled by even a setup where the graphics cards alone cost over $1000. Please list the games you wish to play. Also, how long do you intend to keep the computer for?
4. Awesome. I don't know too much about video encoding but that helps for anyone else who looks at this thread and has an answer. So when I look at the CPU and suggest one, I will be referencing the "video encoding" benchmarks from this site:
http://www.anandtech.com/bench/CPU/27
There are 7 benchmarks for me to look at. I would also like to note that in some cases the CPU scores are very close. I have noticed that when they are very close, strange results are listed. Such as two CPUs with the same architecture, one with a higher clockspeed, but the lower clockspeed winning. At this point, I consider them to be the same.
Now onto my suggestions. These suggestions are based on USA prices from Newegg.com. After euro to dollar conversion, we are looking at about $1200 USD. The following is what I would build for myself if I were doing what you do.
CPU: $160: Phenom II 955 BE. C3 stepping. Because it will overclock the same as the 965 C3 stepping but is $20 less.

Motherboard: $120: Excellent motherboard with 8x crossfire capability.

Memory: $120: Mushkin because really, they are the best. And 7-7-7-20 timings at 1333 MHz is hard to beat. Get 8GB instead of 4GB if you intend to keep this computer for more than 2-3 years without upgrading.

Hard drive: $90: samsung F3. The fastest for the price and apparently the quietest. 1TB for all that video encoding. Get as many as you need.

Power supply: $90 :650W corsair. Enough for the system and perhaps even more. Very well reputed brand.

This leaves $620 for a case and power supply. This is enough for a single radeon 5870 and one expensive case. Or you could stretch your budget and add a second 5870 for better graphics performance.
Personally, I would get the case and single 5870. Game and see how you like it. If you find it insufficient, grab a second 5870 and crossfire them.
I am not fond of multiple GPU systems myself. The performance gains are not worth the cost of the cards in most cases. I have also experienced stuttering with the old GTX295 dual chip card even with the latest drivers. I am unsure if stuttering issues have been completely resolved with crossfire and SLI on the new cards. Personally, I would get the single 5870, wait two years and upgrade to a radeon 7870.
Anyway, that's my take. Feel free to ask any questions or let me know more information to help
