I want your GTX460 vBIOSes!

Depends on what 3d app/game your running, but generally NO. The 256bit (1gb) mem models are not held back by memory bandwidth, so you will gain more from your core clock OC.

I would OC your core first, get it nice and stable, and then start on the memory.

Wrong. Set your core clock to say 880MHz and your memory at 4GHz, now run the GPU tests in something like vantage at max resolution with AA/AF, then do the same thing again only with your memory at 4.25GHz. You will get a 200-300pts GPU score increase. At 880/4000 the card is starting to get bandwidth limited for higher resolutions.
