Need advice/review of my build

[quayu]

Hello,
Im going to build new PC from scratch. Atm im thinking about the following config:

CPU: Intel Core i7 4770K
Board: MSI Z87-GD65 Gaming
GPU: MSI GTX 770 Lightning 2GB (or Gigabyte GeForce GTX 770 4GB)
RAM: G.SKILL DDR3 2x8GB 2400MHz CL11 XMP RipjawsX
HDD: Segate Barracuda 3 TB
SDD: Crucial m4 128GB
Case: Cooler Master Haf XM
Power Supply: Thermaltake Evo Blue 2.0 750W 80+

Im going to use this computer with 29" LED display. Im also going to connect HDMI projector to it. This system will be used for gaming as well as programming and some office work.
My first question is about the graphic card. Im not sure if 2GB on MSI Lightning is enough for those 2 displays, that is why im also considering 4GB Gigabyte. Secondly, I will be grateful if any of you can indicate if any component can be replaced with better/more efficient part with the comparable price.

Regards

Check into the new Samsung 840 EVOs, they're pretty comparable to the Crucial M4s, and may be competitive in price, not 100% sure though as I haven't looked up Crucial in awhile.

As for the video card, the amount of memory won't affect your ability to drive those two displays much (i.e., 2GB should be more than enough), however, for gaming purposes, the 4GB of video memory will last you more in the long-term over the 2GB.
