I used to get irritated that Fry's employees were generally clueless, but then I realized that I knew more about computers and technology than the vast majority of salespeople from any store, so now I just generally completely ignore them and rely on my own knowledge or look up information ahead of time or on my smartphone when I'm there.
I'm in Hillsboro Oregon, so I know the Fry's store you're talking about very well. I used to work for Hollywood Video corporate office as tech support for the stores (around 98-00), so Fry's was right nearby and I could go on my lunch break or after work. I also lived in Phoenix Arizona for 5 years, where they had 2 Fry's in the area, so I can confidently say that the clueless employees aren't just a Portland area thing for Fry's. :) Although you do get the occasional salesperson with a clue, generally in the CPU/memory area.
Now that I live and work in the Hillsboro area, Fry's is a long drive for me (almost 30 miles each way.) I've found much the same prices at a locally-owned computer store called ENU (www.enuinc.com), and it's only a few miles from my house. Doesn't have near the huge selection of Fry's, but has good prices and a pretty good selection of common computer items, and the salespeople are fairly knowledgeable. It's just a big warehouse room with no frills, and they generally sell their items as OEM white box packaging, so they keep the costs down. You can get better prices online usually (although not drastically cheaper, especially if you add in shipping), but if you need something right away you can't beat them. Definitely recommend them unless you're looking for hard drives - Fry's has much better prices on hard drives than ENU.
On topic of Best Buy though: never shop there. In my experience their prices aren't that great, and selection isn't that great either. Staples and Office Depot actually tend to have better prices, and have large sections of computers now. Bought my Asus tablet at Office Depot, they have just about every model available of tablets. I think it's Office Depot and other office supply stores that is really killing Best Buy.
