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.
The performance of a GPU is typically measured in GFLOPS, which stands for billions of floating-point operations per second. This metric indicates how fast the GPU can perform complex mathematical calculations.
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
The latest graphics card model offers around 20 teraflops of GPU performance.
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.
Photoshop is more CPU intensive than GPU intensive. This means that the performance of Photoshop is more dependent on the power and speed of the computer's central processing unit (CPU) rather than the graphics processing unit (GPU).
The motherboard... Interconnects - CPU - HDD - RAM - Optical Drives - GPU - PSU
