I'm getting some choppiness in my newest games, so looks like it's to overclock a bit.

It's a Hercules GF2 Ti with a blue orb and ram sinks.
I've had it up to 270/445 but was only getting 4908 3dMarks, which seems a bit low.

I'm not going to be overclocking the FSB yet as the northbridge does not have active cooling.

What do you guys think?
