I've been looking at those exact benchmarks most of the day today and I can clearly understand what you mean and I do agree, but it all comes back to preference, it's kinda a big deal to switch from AMD when you've been running that the whole time to INTEL. Or vice versa.. I'm definitly considering it but...
http://ncix.com/ is also quite decent, although it looks like anitec.ca is cheaper in some instances.
I see the E6600 for 385.95 CAD at Anitec, for God's sake. Don't tell me you can't afford to spend another $50. That's frigging insane. Get the 6600. And obviously a board for it, but that's implied. And there's no good reason to spend $300 on a board. ESPECIALLY if it's AM2. EVEN if it's CAD. I wouldn't spend more than $160ish myself, but then again that's USD so let's say $200 CAD. No reason to spend that much for an x1900XT, even if it is 512MB. Get the x1950pro or get an 8800GTS/GTX, your choice, get the GTX if your budget allows it.
I'd yell at you to get some cheaper RAM, as that's fairly expensive, but it doesn't look like any really exists in Canada-and it is, after all, quality. I prefer Seagate myself when it comes to hard drives, but whatever floats your boat. $200 for speakers seems a bit much, but I'm not the one buying it, now am I? I can't think of a good reason to spend $120 on a case if it doesn't come with a decent (read: Antec or similar, 500W+) power supply, though I'd recommend buying a replacement one if you get an 8800 series video card. Seasonic is pretty good, and the price is actually decent.
