Hey there, i use a program called: MSI Afterburner to OC' and tweak my Zotac GTS 450
It works flawlessly and has a in-game HUD-like thing which displays in the top left (by default) which shows the temps, Speed, and FPS and more, so you can easily get a reading to see the effects the program has done whilst tweaking.
Very neat program i must say! Highly recommend it
I run my GTS 450 @
810 Mhz Core
1620Mhz Shader Clock
30-50 Fan Speed (Depends on my gaming situation and my temperatures my GPU gets during play)
I looked at your photo, and i think you should be ok, i only have 1gb vram compared to your 2gb so it should be all good to go.
Hope i could help
