Is the Samsung 850 EVO a good choice for me?

I am looking to upgrade the storage of my PC. This is my current build:

CPU: Intel Core i5 3570K
CPU Overclocking: 4.3Ghz - Moderate (+26%) Overclock
CPU Cooler: Xigmatek Loki SDS963
Operating System: Windows 7 Home Premium (64-bit)
Motherboard: Asus P8Z77-V LX2
RAM: 8GB Corsair 1600mhz Vengeance (2x4GB)
Hard Drive: 1TB S-ATAIII 6.0Gb/s
Optical Drive: 22x DVD±RW DL S-ATA
Graphics card: NVIDIA GeForce GTX 670 2GB
Sound card: Onboard 7.1 Audio
Case: Zalman Z11 Plus
PSU: 650W Corsair TX V2
Warranty: 3 Year SureCare Warranty

I use 3 1080p Dell 60Hz IPS monitors. I do gaming, work with unity and do lots of multitasking. I am also considering a RAM upgrade to 16/32GB

I have been looking at getting an SSD and the 850 EVO caught my eye. I need at least the 500GB model but will happily consider the 1TB model if it has any performance benefits. Likewise I will buy the PRO rather than the EVO if the increase in speed is worthwhile.
I live in the UK and right now SCAN seems to be the cheapest supplier.

Speed increase is minimal between the Evo & Pro - I use 500GB Evo drives on laptop deployments on a weekly basis. I have yet to have one fail and they're pretty zippy. That's what I will continue to buy unless they release a newer model with high read/write speeds for a similar price point. You can on occasion get ridiculous deals on their 1TB option but the performance differences are non-existent, it would just be about capacity and convenience.

If you are not going to do enterprise level writes (like website or database application being used by hundreds or thousands of people) then the EVO will be a great fit for you.
