Skyrim Stuttering - CPU or HD?

I have a Q6600 @ 2.4GHz, 6GB DDR2-RAM @ 667MHz dual channel, WD 640GB 7200RPM hard drive,and an EVGA 1GB GTX 560. I can put the game on High settings and get decent performance (25 - 45 fps) with minimal stuttering. However, putting it on Ultra results in a lot of stuttering, though FRAPS doesn't show much loss of FPS. According to my research, the most likely bottleneck is my CPU, but I'm thinking it could also be my hard drive having issues loading textures. The stuttering is most noticeable after loading a save and spinning in a circle. FRAPS still shows fps of about 20 - 25 when this happens, but it looks much worse to my eye. It still stutters noticeably when wandering around on Ultra, though not as badly as a fresh load + spin.

My Q6600 will overclock stably to 2.8GHz on stock cooling. The problem is that it turns my tiny office into a sauna when I do that. Since I have central air, cranking up the A/C isn't really an option as it would freeze the other occupants of my house. Would a fast Phenom (~3.0Ghz) eliminate any bottlenecks? Would an i5 run cool enough?

If the hard drive is the problem, my options are limited. SSDs are expensive and not nearly big enough to hold all of my "content". I'm not sure if a hybrid drive would solve the problem or not.

So am I better off getting a new CPU or hard drive?
 
putting the frame rates aside, the 1gig of video ram isn't helping you much. if you're running 6gigs of ram ( odd amount ) they aren't running in dual channel mode are they ? try running in a lower resolution that your monitor will handle see if it helps any. try increasing the virtual ram....... you're having off loading issues because of the lack of vram.

OC'd to 2.8GHz CPU/390MHz FSB/780MHz RAM and saw little improvement. I then disabled the official hi-res texture mod from Bethesda, dropped AA entirely (not strictly necessary at native res) and the vast majority of my problem went away. Given that disabling hi-res textures seems to solve the problem, you may well be right about the VRAM, but it seems to do just fine with the standard "High" setting for texture size. I'd rather not lower my resolution below my panel's native resolution (1600x1024), or I would need to turn on AA or FSAA.

My RAM configuration is 2x2GB + 2x1GB. According to the BIOS, CPU-Z and Memtest86 it's running in dual channel mode.
