So what's a good overclock on a Geforce 5900 non ultra?

I have a Gainward 5900 non Ultra 128MB

I've been able to oc to 425 core and 850 ram from the stock 400 core and 700 ram. Is that a decent jump?
My room is very hot so that's as far as I pushed it

Search the forums for "5900" and look for overclock speeds. Your ram is a good jump, but the core isnt that high percentage wise.

I have a Shuttle XPC btw. I installed a 250W cool/silent power supply in place of the standard 200W and now I can o/c my GPU to 460mhz
