Hello
I am buying an AMD A64 x2 4000 + and a video card with GPU NVIDIA 7300 GS 256 know when it can lead to serious micro with sink, now increased to 2.5GHz and has temperature of 33 º and 44 without doing anything º - 45 º playing cod4, you can?

Another question:
Can an overclocked video card Geforce 7200GS FV-model N72SM2DT? And the plate comes with a program for this but when you restart the computer at 450 MHz is the initial speed.

Thanks
