This was an excellent gaming build, that also handles productivity well. It also looks the part, without being garish. While it exceeds my personal needs, that's only a matter of scale, which could be addressed easily enough.
I was not going to be critical, until reading the other comments so far, so I'll add this:
1. Last quarter's $2.6K PC was the quintessential Professional's PC, with a classy, quiet case. I might have kept it for this build, or used something equally classy from Lian Li.
2. Please keep the professional, all-around focus at this price point. Particularly considering today's economy, the typical gamer doesn't have $2K to spend on a strictly gaming PC. I like these articles when they represent what someone might actually build. As such, this is a very nice machine (I'd love to win it!), but who exactly would build it? See next point, as it may pertain to the professional users who would have the money.
3. This is more a question that a criticism, but is Kepler's reduced Compute performance a possible issue in an all-around and/or professional's PC?
4. Kudos for not believing you had to spend the whole budget. For an all-around PC, there's enough left for the BD drive.
