SG300-10MP / Fiber From Home Office Switch To Equipment Rack?

I just installed a 10 port Cisco SG300-10MP in my office, 9 of the ports are already in use. Connected to it are

PC
Laptop
Notebook
WIFI AP
B&W laser printer
Color inkjet printer
IP camera
Squeezebox SB3

Cat5e connection to basement HP 1810G-24 switch All of these devices are connected via a single Cat5e cable that was installed when the house was built. I had to re-terminate both ends of it when I moved in because the existing terminations were done very poorly. I have no idea how or where the cable is routed, nor what the quality of this Cat5e cable is. It did pass a test using my cable tester.

This single Cat5e is connected to my main HP switch in the basement equipment rack. Both of these switches have mini-GBIC ports that can utilize SFP transceivers and fiber. I priced out 2 MGBSX1 compatible modules along with a 30M multimode fiber patch 'cable' online at under $150. Although it would require at least a couple hours of work (including digging around in the attic and crawl space and drilling some holes), but running the fiber to the basement is very doable.

My question to my far more experienced forum members is if the performance gains would be worth the effort?My server is in the basement, and despite having an Intel GB NIC in my PC I am seeing read speeds of ~23MBs and writes of ~49MBs to/from my it. My server has teamed GB NICs (802.3ad LACP Layer 2) connected to trunked (LACP) ports on my HP switch.
