Will an overwhelmed network card slow computer performance as a whole?

I'm running a fun little experiment as I write this. I'm deliberately slamming my wireless card. I'm pulling data via Dropbox, pushing data via CrashPlan, pulling data via Google Drive, and pulling data via YouTube.

- Disk
Disk Queue Length is spiking in the 4 to 6 range.
Total I/O Reads Delta is hovering around 100 to 300.
Total I/O Reads Delta is hovering around 100 to 200.
- CPU
CPU utilization is bouncing between 30% to 60%.
- Memory
Memory utilization is at 58%.
I still have 1.2 GB of "Available" memory.
- Network
Network download utilization is maxing out at about 1.2 Mbps. (I'm in a coffee shop, I'm confident I've maxed-out the DSL.)
Network upload utilization is maxing out at about 0.05 Mbps (truly anemic).

I have achieved true sluggishness. Here's the question, is the CPU "agile" enough to not let the overwhelmed wireless card interfere with processes that aren't using the wireless card. When, for example, I open a big Word document and it takes 30 second to open. Can I count on the slow speed being a result of an overwhelmed HDD and CPU and not being a result of the overwhelmed NIC?

What are the specs on the CPU?

What are the specs on the HD?

How "big" is the "big" Word Doc?  How long does it take to open it if you are not doing anything on the network?
