Music Production System (ableton, reason, studio one)

Hello everyone, I'm looking at building a medium budget PC for music production and a small amount of gaming. The main DAW i will be using is ableton Live 8 which is only 32 bit (except the beta). It also does not support hyper-threading. The DAW its self does not require much power, but with a big use of plugins this causes issues with the CPU. I also use a firewire audio  interface (m-audio 410), so i need a motherboard with firewire.

This is what i have come up with a build:

CPU: Intel Core i5 3470

Motherboard: ASRock Z77 Extreme6 Motherboard

Memory: Corsair Vengeance CML16GX3M4A1600C9 16GB (4x4GB) DDR3

Storage: Intel 330 Series 120GB SSD (os and daw)

               Western Digital WD Black 1TB WD1002FAEX (samples, plugins and games)

Graphics: Gigabyte Radeon HD7750 2GB Overclocked

Power: Antec VP550P 550W Power Supply

Case: CoolerMaster Elite 335U with 420W

Total : $873.00

If there are any recommendations for this system, that would be amazing, as i am looking for something that will handle the latency and CPU and not need to be upgraded for a while. Also if there are any cheaper options available, it would be much appreciated.


Thanks
