On the first point. Intel. Intel. Intel. I was a die-hard AMD man for YEARS Span, from the K6-2 all the way to the 939's...but AMD just sat on their laurels after getting X86-64 out the door, and Intel just beat the everloving crap out of them not just in regular day-to-day stuff, but things that AMD used to win handily, like gaming and media encoding.
Honestly, what finally sold me on them was how cool the Core2 processors run. When you can take a stock 2.66 chip and OC it to over 3 GHz using the stock cooler...you've got a good chip. I doubt you're into OC'ing heavily though (it's risky as shit, but I like pushing the barrier...till I smash headlong into a wall).
Intel got their act together after the fiasco that was the Presscot cores, and they've been getting better since.
Honestly, if you're dead-set on AMD, I can't tell you shit about AM2 vs. AM3. The last AMD machine I have is my 939 HTPC, and I stopped keeping track of their sockets.
Now....the i7-capable motherboards are out there, yes. The X58 chipset is an awsome chipset that can do some amazing OC'ing and the i7 will be the socket of choice for at least two years. DDR3 is faster than DDR2, though not by leaps and bounds.
HOWEVER...right now, you are paying a HEAVY premium for those parts. Any i7 capable Asus board is over $200 minimum, the cheapest i7 processor is $288, and DDR3? Do yourself a favor, don't even look at DDR3 prices vs. DDR2 prices right now.
Now, I read HardOCP for all my hardware news. Their methodolgy is not "run 10 synthetic benchmarks and call it a day", no, they go by "best playable" using real-world scenarios and differing settings to try and maintain 30 FPS or better.

Our E8500 solidly held its own in FarCry 2 gaming at 1600x1200 resolution and above.If you want a full rundown of what hardware I'd put into my own machine right now if I was building one Span, just say so, and I'll make you up something killer within whatever budget you're looking at (hopefully without screwing up the USD-Euro conversion)
