A ‘grave disservice’? Please notice that the OP also doesn’t mention specifically wanting to stay with Windows.
Look, if the OP were, “I want the best PC for playing games”; yeah, it’d be silly to recommend a Mac.
If the OP were “I want the best PC for doing some hard-core CAD work”, it’d be pretty silly to recommend a Mac.
If the OP were “I want the best PC to work with my company’s proprietary software that only runs on Windows”; it’d obviously be silly to recommend a Mac.
Hell, I’d be the first to admit there are many situations where it would be silly to recommend a Mac, especially if, like you say, they want to stay in the Windows world. No problem there.
But, the OP is “I want the best PC for video editing.” For video editing. No mention of wanting to stick with Windows only. Come on now, it’d be silly for Macs to NOT be brought up. Why? iMovie and iDVD for novices. Final Cut Express for mid-level work. Final Cut Pro and DVD Studio Pro for professional work. All excellent programs for different levels of usage, and absolutely worth a serious look for someone serious about video editing. Apple has sought out this specific market, and done a damn good job of it.
Even though I’m a Mac user, I would never blindly tell someone they should buy one. Get the right computer for the right job, and consider all the factors. But a ‘grave disservice’ would be telling someone to ignore some options, of which, in this specific case, a Mac system is a very good one.
Moving on from that… I have a question about the benchmark tests – and this really is a question, not a statement disguised as a question, because I really don’t know the answer. It’s also a question that yes, I’d still be wondering about even if after the G5s are released they are the clear leader in these tests.
Do a few notches one way or the other on a benchmark test really make a real-world difference to 99% of computer users, other than bragging rights? I mean, yeah, if you’re doing hard-core Photoshop filters all day long, or something that intensive for long periods of time, that extra time that the extra speed buys is going to add up. But does this make a difference to most of us? To put it in terms of the OP, unless he’s going to be using his computer to render the next Pixar film, is it really going to make a difference to him (speaking purely in speed terms here, no other factors considered) if a top of the line Pentium is proven to be a little bit faster than a top of the line G5? My creaky, old, low-end G4 runs Final Cut Pro just fine. Some rendering could certainly be faster, but I know it would be just fine on a newer system. As long as it runs the programs you need just fine, and isn’t slow enough that it’s costing you time, does it really matter to most of us?
