I've made few updates to my build considering your comments, and now it looks like this:
CPU: Intel Core i7 4930K Extreme Hex Core
Cooler: Thermalright Silver Arrow SB-E
MoBo: Asus P9X79 PRO
GPU: EVGA GeForce GTX 770 SC 4GB
RAM: Corsair Vengeance Low Profile 32GB (4 x 8GB) Memory Kit PC3-15000 1866MHz DDR3 DIMM
SSD: SSD 256 GB SAMSUNG 840 PRO
HDD: HDD 2TB WD BLACK
Case: FRACTAL DESIGN DEFINE R4
PSU: Corsair AX760
System: Windows 7 64 bit Pro
Monitor: Dell u2413
This build costs £2121 which would leave me an option to get second Dell u2413 or maybe something like NEC PA241W + one very cheap display. But is NEC really that much better than Dell or Asus (it costs almost 2 times more)?
Thanks for your input Kadri. You are probably right that this is an overkill, but I'll stick to it
If you don't mind, could you explain what's wrong with Samsung SSD?
Oh, that's good news That makes buying EVGA GTX card a good choice if they will release 6GB version in next 90 days, since they have a step-up program.
Thank you guys.
