The next step

[bonghitter400]

I have achieved 2.7G (245 x 11) with my amd 4200+. My temps are 33c idle and 41-42c while under load. The highest temp I've seen is 54c while running SuperPi and downloading 4 games at the same time. I did it just to see if I could hang it up or something and the computer just tore through it like it was nothing. (I love the Vantec STG-100 watercooling kit- I would recommend it to anyone)
Anyway, the system is perfectly stable and runs cool but I can't help but wonder how much faster it could be.
I have the vCore turned up to 1.45 volts. How much more could I be able to overclock this cpu and what voltage would be sufficient? Does the multiplier make a whole lot of difference? For example I have seen people with 600x6 and people with 400x9 to get 3.6G Which is better?
Anyway here's a screenshot of cpuz. Thanks for any input!

I am a heavy gamer so benchmarks do count to me. My bes score on 3dmark06 is 5345. Does that sound sufficient for the rig that I'm running? The specs are in my signature.
Thanks again!
