Hi pvrvideoman,
I suspect that your hard disk layout limits your system.
The RAM can't be it. I have 16 and I NEVER saw more than 3.6 GB of it used. Remarkable as I had set my system to never swap memory content to disk as per Win7 parameter.
Your system spec says 250 GB HDD. Even assuming thats a SSD you seem to have only one disk. In this case all OS read/write AND the heavy read/write originating by video editing would go to that one poor disk. In my setup video IN and video OUT are always going to different disks and the OS and app data are on yet another (SSD) disk not affected by video editing. When I play around with doing everything on one disk the effect on duration of producing videos is VERY visible.
Again - thats just guessing from the system info you gave in your earlier post.
A comment to your XFX video card: Thats indeed a powerful device but to my recent assessment will not really be as efficient for GPU acceleration as you - and I - probably hoped.
I just reverse-engineered similar questions having bought/built my system already and trying to get the most out of it.
See my findings in the following post

What this seems to indicate is that any discrete GPU is choked by the still relatively slow PCIe connection while the - much weaker - integrated GPU in the intel core i7's brings the desired acceleration courtesy of its fast bus transfer.
You see me wording my findings cautiously as my humble experiments aren't providing scientific evidence.
