Few quick layout comments
I liked the idea of the format, but the realization was a little short. I prefer form over function, but I still loves pretty pictures, so the format was a wash.
First off, I agree that the benchmark page was very nice--the less scrolling, the better.
Which brings me to my next point: repeat the navigation elements on the bottom of the page, or just move them there. I don't like having to scroll down to read the text, then having to scroll back up and down to read the next column, then back up top to move on. It kind of defeats the point of fitting the page to certain browsers in the first place...
...And who uses 640x480 anymore? Most new computers start at 1024x758 nowadays, and 800x600 should cover pretty much every other computer for the past five plus years. Palm PCs aren't above 320, so they're gonna have to scroll anyway. I doubt they make up more than a few points of your readership, anyway. Browsers generally have more usable width than height--there's a reason magazines use columns, and their fixed format is a big part of it. You can just as easily inline images with wider (or even a single) columns, IMO.
I like the ability to change the font size more than I like a nice background picture. Please incorporate this into your next revision, or consider using Flash and allowing the page to be stretched to the browser width, much like a PDF. The fonts are barely large enough on a 19" at 11x8, Normal Windows font size.
I'm not sure why you switched column layouts and line spacing, either. A consistent presentation is more, well, "professional," IMO. I have to use quotes because I still have a hard time considering gaming hardware remotely professional.
I'm not sure why you went with polar color schemes, either. I'd prefer if you stuck with light on dark (or vice versa) throughout. The text box on the Tiger Woods page could've been a little more opaque, too.
An interesting start, Joe, but I'm waiting for you to use some of that DHTML/JavaScript magic to turn the tide in favor of ease of use.
Ben, I'd comment on the review, but I didn't really read it, just skimmed--I'm kind of reviewed out recently.
I'll give it a better look-through later, though the 9000 and its ilk really don't interest me. If I'm aiming for the low end, it'll be 8500 or 4200. The next step I'd consider is DX9-class hardware, so I'll be waiting for the 9500 with interest.
You and other reviewers might consider researching pricing in markets outside your hometown/main audience, as well, as the price differences may change relative scores considerably. Perhaps incorporate a sub-rating system (speed, quality, polish, price), so it's easy to amend the score for different markets.
Hope you both found this criticism constructive, and take it as such.
