Well, is the X6800 really worth 4 times the E6600? No. Will some people still pay for it? Yup. You're not missing anything, that's just the world of enthusiast computing. Honestly though, if you had the P5K and decided you wanted a RAID controller, and an extra NIC, and a wifi adaptor, chances are you'd have to spend quite a bit of that 90 dollar difference. So, even though it's kind of a rip, it's much, much less of a rip than say...the 8800 Ultra. Plus you get the extra bios options and better heatsinks.
BTW, does anyone remember the good old days before C2D's arrived when a top-of-the line mobo rarely ever crept above $200? I miss that.
But I think the P5K Deluxe is worth it
so far we have
1) Wifi adapter
2) Black PCB
3) Advanced BIOS Options
4) 6 Sata Ports (4 on normal)
5) 10 USB ports (normal 12)
6) Bigger HS solution
7) Dual LAN
8) ICH9R
9) Better Audio Codec + Optical Audio Jack
10) **Most Important I would say** Better OC?
So far P5B Deluxe had most of the best OC in most review pages.
I don't think anyone will be able to tell you anything definitive about the comparative overclocks of those boards. I know the DS3 is supposedly able to go over 500FSB with a dual core, but that's it. Apparently this chipset overclocks just as well as the P965, and possibly a little better. More reviews should be popping up all over in the next week, so hang tight.
PCIe 2.0 isn't going to be a big deal for a little while, at least for 2 more years. At this point, nothing needs the extra bandwidth. Eventually, the big high-end vid cards will adopt it, probably starting sometime next year.
Uh, from 2 to 3Ghz is a pretty big jump, and I'm not sure the P5K would be the best choice for that. The P5B vanilla was a pretty lame overclocker. Further, you'll need better than stock cooling to run a chip 1Ghz over design freq.
Wow, that's impressive. I would still invest 40 bucks in a good aftermarket cooler if I were you though.
