Graphics Processor Unit
On the graphics card.
GPU-Z is a way ^^
It highly depends on the computer, but it's usually either the GPU, Power Supply or CPU. With GPU and Power Supply generating the most heat normally.
CPU or perhaps the GPU.
I'm the OP on this question and I just want to add that the computer is an HP Pavilion and the GPU change in question is changing from a Geforce 9100 to a Geforce GTX 650
GPU stands for Graphics Processing Unit. It is what is inside a video card that processes all of the video being sent to your computer screen. - ElectroGoofy
If done incorrectly, overclocking can only damage the part that you tried to overclock (resulting in a burned-out chip which will almost always require replacement) or prevent the computer from starting up (not enough power to start up the computer).
Go to a computer hardware store or online, purchase it and go home.
Yes, in fact you should. The Central Processing Unit (CPU) is the element in your computer that does the actual computing. The Graphical Processing Unit (GPU) is part of the Video card which renders the graphics you see on screen.
gpu is a graphical processing unit which ables you run high definitions graphics on your PC, which are the demand of modern computing. if you want to run windows vista ultimate edition then it is better if your PC has a gpu. it helps you to get better 3d views. nividia is very well known for it's gpu.
The motherboard... Interconnects - CPU - HDD - RAM - Optical Drives - GPU - PSU
a lot of it depends on what sort of hardware you're running and whether or not you are overclocking any of it or running it at default speeds. usually in order it is CPU gpu northbridge psu ram hdd but keep in mind that any of these can shoot to the top of the list depending on what you're asking of them. it is probably better to look at it in terms of what is most worth keeping cool and that list is relatively more straightfoward; in order, CPU gpu ram northbridge hdd psu best of luck
