Quick update on the components.
Not very interesting discussion about SSD speed and GPU pricing.Warning: Spoiler! (Click to show)
I found out that Samsung 840 EVO 500GB is nearly equivalent to the Samsung 840 PRO 512GB is term of performance. It was highlighted by few people out there such as in this PCMag article (http://www.pcmag.com/article2/0,2817,2455429,00.asp
Newegg has the initial Pro 256gb at $190 ($0.74 per Gb) vs the proposal Evo 500gb at $260 ($0.52 per Gb). It think that would be the sweet spot for my heavy use of Lightroom. Warranty is 3years ... so I don't care about TLC being more fragile than MLC.
I looked up into the Samsung website and find the datasheets (see below) that confirms all that.EVO 840 datasheet (link)

I'm planning to switch my proposal EVGA GeForce GTX 770 Superclocked ACX (02G-P4-2774-KR) for the EVGA GeForce GTX 780 Superclocked ACX (03G-P4-2784-KR).
Newegg is $369 vs $509 for nearly 25% more power. Considering that Maxwell won't enter mass production until a lot later this year it makes a more powerful card a little more valuable in regard of its future depreciation. I decided to switch after looking at my budget back in 2009 when I bought a HIS 5870 for $470 and it last me 5years. It's still a solid card for a lot of applications. I'm looking to replicate the power/pricing ratio decision pattern.
