One noob's noisy GPU

[Moomintroll]

Hello,

I'm relatively inexperienced when it comes to building computers and was hoping for some advice. A friend sold me his redundant pc and initially I was really happy, although now have found that the graphics card is quite loud.

The build:

Coolermaster Silencio 550 Silent ATX Case with GX 550W PSU
MSI 970A-G46 Socket AM3+ 8 Channel Audio ATX
AMD Bulldozer FX-8 8120 3.1Ghz Socket AM3+ 8MB with CM Hyper 212 EVO
2x 4GB DDR3 1600Mhz Ballistix Sport Memory
2TB HDD

I don't play any high end games (maybe 360/PS3 equivalent titles such as Fallout: New Vegas), so am looking to upgrade primarily for sound-minimizing purposes only (although being able to play more graphically intense games would be of benefit). I've been overwhelmed by the amount of information about pc building on the internet, it's hard to find somewhere to start. What's the best option for the components I have? Will I need a new MOBO or processor?

Thanks in advance.

Derp. It's a Radeon HD 7750. And yes I have.

I've read that it's renowned for being noisy. I guess around £200. I'd like some advice on the 'best' build I can do with the components I have, and understand that the GPU is something that is worth spending money on.

Awesome, thanks. Is there anything else I can do to improve the setup? I was reading that the processor is good for overclocking.

Which PSU would you recommend I replace it with? Is 650W sufficient for my build with a new GPU, or will that be dependent upon more specific details of the graphics card? I want it to be as quiet as possible, and as energy efficient as possible too.

So, with the release of Fallout 4 and the funds to upgrade my system I'm looking at purchasing:

EVGA Supernova GS 650W '80 Plus Gold' Modular Power Supply

MSI Gaming GTX 960 4gb

Will I need to get a new processor too?

I have a 1920x1080 monitor so won't need to run it at any larger resolutions.

Thankyou both for your replies. How does the 970 compare to the 960 with regard to noise?
