Hello, everyone.

I am thinking of buying the MSI NVIDIA NVIDIA GeForce GTX 750Ti/N750Ti TF 2GD5/OC 2 GB GDDR5 Graphics Card.

I own a Intel Pentium E6600 Dual-Core CPU and 2+2 Gb DDR3 RAM,

Q1. Will the CPU in any way affect the performance of the GPU?

Q2. Please suggest a PSU which ensures proper functioning of the card.

Q3. If possible, please suggest another better variant of the Nvidia 750Ti.

Q1: Put simply, yes. Your over-all CPU power does have an effect on the performance of your GPU. This is because the CPU is what works together with the GPU to make use of all its power. For example, if you were to use an AMD Radeon R9 295X2 (An extremely powerful; card) and accompany it with a 10-year-old Intel Centrino, then your performance would be SEVERELY throttled by the slow CPU.

In fact, think of it this way. Your computer is a highway. the cars (data) on the highway all have to go at a certain speed limit (your CPU speed) the higher the speed limit, the faster the cars travel between the CPU and the GPU, since the CPU tells the GPU what to render. Your RAM is the width of the highway, so with more RAM, more cars can pass...

Your RAM is the width of the highway, so with more RAM, more cars can pass through, but if the speed limit is too slow, the cars can't travel fast enough from the CPU to the GPU to deliver its rendering instructions.

Slow CPU + fast GPU = bad performance.

Q2: Any standard 80+ Bronze Certified 850-Watt PSU will effortlessly support this card.

Q3: As for a better variant of the card, I believe it's a bit more expensive, but I'd go for the MSI GTX 750 Ti 2GB Twin Frozr Gaming OC if I were to get a 750 Ti.
