This can't be right...the stock speed seem a bit low:

Anyway, forget Vtune, go download MSI Afterburner and use that instead.
My 9800GTX+ (aka GTS250 after rebranding) Core/Memory/Shader would overclock to 785/1200/1950. I've seen others overclock to higher, but I guess I just unlucky and draw a less decent card, but I'm still happy with the overclock. You can use my figures and start from there...hopefully you'd have better luck than me and got a better card.
After you overclocked, test it on benchmark etc. If you see artefacts or little white lines/bits appear on screen when running games/benchmarks, you'd need to lower the core speed. If you see tearing, you'd need to lower the shader clock. As for memory, I'd suggest you overclock it the last so that you can make sure Core and Shader clock are fine, and then when you overclock the memory, you'd know you've clocked it too high if something abnormal shows on screen. I would however suggest you not go above 1250 for memory.
As for voltage, I'd suggest you not to mess with that, as my 9800GTX+ would reaches max 80°C at 100% GPU usage when running Heaven Benchmark at stock voltage.

Well, if you want to be sure, go download GPU-Z and see what it says about your GTS250's speed. You gonna need it for overclocking anyway.

It doesn't matter. Althought it says it's for MSI cards, it works with other brands too- my 9800GTX+ is XFX.
MSI Afterburner not only make overclocking easy, but it has feature of logging GPU temperature, GPU usage and other things. It's very important to keep track of the GPU temperature when benchmarking.
There's no harm trying the MSI Afterburner...most of the member here use that. If you don't like it after trying, just uninstall it and use you exist tool.
