My other PC specs are
Q6700@ 3.0 Ghz
Zalman 110mm CPU fan
4 gig of DDR2 1000 Gskill ram
700watt Cooler Master p/s
320gb 7200rpm seagate H/D
Both the processor and the memory are bottle-necking your performance. The Q6700 is fine for gaming until you get into the high range GPUs. It will bottleneck anything above an HD 6750 or a GTX470 (for those cards it is adequate). Overclocking the chip will not help terribly much because it is an older architecture with less on-die cache and features than the Q9550.
However, you will see better performance on the i5 2300 to i5 2500 than on any of those older Core 2 Quads (and for much less money). The value on your system will soon be diminishing with the release of Ivy Bridge and Bulldozer.
You might want to think about purchasing an i5 motherboard, a single 4 GB module, and something like an i5 2500. Then you can sell most of your current parts and get anywhere from half to two-thirds of your money back. That would be an ideal set-up for that fantastic card.
