Nvidia Geforce 7500le overclocked

[nickademus]

Hey, I recently tryed my hand at overclocking my video card(I did know obsolutely nothing about this), using Riva Tuner 2.06. What I was wondering is if I have done it correctly or if what I have done has even made a difference. All I have done is gone to the system tweaks tab and set it on 3d performance and then set the core clock to 610(was 550)mhz and the memory clock to 880(was 800)mhz. I havent tryed anything else as of yet. I was just wondering if this would have had an effect on improving my gpu performance. I have tested it using PC wizard 2008 and it gave me a few frames /s more when I ran the benchmark but I would just basically like to know how much higher could I set the memory and core clocks and what else could I do, using riva tuner, to improve performance.

Thanks,
