Hi, i currently have a problem on what to upgrade. i have around £100-£150 and have a few ideas in mind but cannot come around to making a decision. I have also been having some FPS issues, whjen my GPU is at stock clocks it works worse than when i underclock it. in battlefield i rarely hit 60!
1. Get a corsair RM750
2. Get a Fx-8320
3. Get a OCZ ModXStream pro 700w plus kingston 120gb SSD
4. Get a kingston 120Gb SSD and noctua case fans

asus M5A99X
Corsair H60

Because you said 1) GPU is at stock clocks it works worse than when i underclock it. 2) psu has recently became very load and annoying.
So I think the problem maybe 1) Is the GPU temp high, overheated? If it is then it will work better under lower temp condition. 2) the PSU try to work hard to power the GPU/CPU so it is louder.
Also what kind the case do you have? Using the software to monitor the GPU temp too.
