New to Mac and Final CutStudio Please help with query on jerky video

I've owned an iMac for about five weeks. Its my first Mac after many years of PC. (Sorry!!)
I bought the Mac to get into FCP editing after using Adobe Premier for a long while. I went for the iMac and the specs are 3.06 ghz processor, 4GB RAM and the graphics card is an NVIDIA GeForce 8800 GS with 512MB RAM
from the About this Mac:
Chipset Model: NVIDIA GeForce 8800 GS
PCIe Lane Width: x16
VRAM (Total): 512 MB
Vendor: NVIDIA (0x10de)
Device ID: 0x0609
Revision ID: 0x00a2
ROM Revision: 3234
Resolution: 1920 x 1200
Depth: 32-Bit Color
Core Image: Hardware Accelerated
Main Display: Yes
Quartz Extreme: Supported
Status: No Display Connected
After successfully installing the Studio 3 software, I loaded some 1080i footage shot on XD Cam from a Sony EX3
For a while all was well and I began trimming down the footage and crudely assembling a rough firstedit.
Then the footage in the canvas window began to play rather eratically - like it was running at 10 FPS. As yet I have not rendered the video its straight off an external drive into the program
Is this normal? Will thefootage out put OK? Am I doing something wrong?
Any help gladly received

Welcome to the forums!
We're going to need some more information to help you out here like:
Where are you storing your footage for scratch? You mention the video "straight off" an external drive into the program but how do you have everything setup.
Are you using a USB or a firewire drive?
What are your clip settings?
What are your sequence settings? (I assume it matches the clips)
Did you get a warning popping up that stated that it couldn't continue to play in real time?
You mentioned that you hadn't rendered, are there any indications on the sequence that it requires rendering?
Have you tried exporting a small portion of your sequence that is "jerky" during playback to see if the final product is actually jerky (depending on export settings and bitrate, you may need to transcode anyway to get smoother playback)?
Although it's an older blog - this has some interesting information about EX-3 workflow suggestions: Sony EX-1/EX-3 and Final Cut Pro, What’s Your Workflow? : SuiteTake.comMy Macs: Late 2013 rMBP w/ 750m; Mac mini G4, 1.25 GHz, 512m ram (server); Late 2011 11" MBA, 1.8GHz i7, 4Gig Ram, 256Gig SSD, HD3000; Powerbook 12" G4 1.33GHz running Debian as a server; Apple TV (1080p version)

My guess would be that the video isn't playing in real time and needs to be rendered or your scratch disk is too slow to read off of. But it's hard to say without knowing what your capture and sequence settings are.
