their site is a bit hard to navigate, but from what I see:
- they don't use dual core CPU's
- their highest end PC uses an Athlon 64 FX (I think 57)
- the highest end video card I saw was a Radeon X600. you can get way better than that.
the site seems to be oriented around trying to make their PC's look really great, which it does pretty well. but they don't get right down to the point. they don't tell you exactly what's in the PC's (which isn't a good sign)
and the fact is, you can build a better PC for a lot less money.
one thing I can give them credit for is their cases, and monitors. their monitors look nice, but they're probabbly extremely expensive.
