Even just after turning on my computer after it I put it to sleep for the whole night, my CPU temp. was around 20-30 C, mobo was around 30-40. But my graphics card automatically goes up to 65C! Even though I just use the internet browser. I'm looking to buy a new one, but not sure which.
Right now there is a Zotac GT 430 with 1GB of DDR3 memory, it is on sale for $30, but I'm not sure if I should get it.

It needs 300 watts and my power supply is 300 watts as well.
I have a NVIDIA GeForce 8400GS with 256mb.
