Nope, just shows how little you know about SSD's other than some obscure "supposed fundamentals" that are incorrectly circulating the internet.

That's why you have Over-provisioning to help reduce write amplification, when an SSD gets full the garbage collection algorithm then gets to work and consolidates partial blocks to provide free space.
However an SSD that is completely full will need to do this frequently.

That's where allot of SSD manufacturers decided to add some Spare Area to combat that problem which is usually equivalent to a single NAND module to assist in wear levelling and to stop the performance hit that occurs when the entire SSD is full and the garbage collection algorithm rears it's ugly head.
Smart SSD controllers (I.E. Not Sandforce based) are incredibly efficient at this.

Now the TRIM command is where the OS will tell the SSD when certain blocks aren't needed which then the SSD will erase, which again increases the amount of space and reduces any performance impact in the long term.

In regards to Sandforce based controllers (OCZ, Corsair SSD's etc'.) they actually use compression, so if you have allot of data that doesn't compress very well (MP3's, Video, JPG images etc') then the controller will need allot more spare area to work efficiently and hence will cause allot more writes needed to be done, but data that the controller can compress will cause allot less writes as it can fit in a smaller space, it's a compromise.

Now some other factors you need to throw into the mix is the type of NAND that an SSD uses, MLC, SLC, TLC all have differing write endurance, which consiquently will play the largest impact on how long your SSD will last.
Another impact is the fabrication that the NAND is built upon, NAND that is built at 28nm will not last as long as NAND that is built at 40nm.

If you want your SSD to last you a *long* time, then just install the OS and core applications and leave it at that, if Windows hasn't done it already move the Pagefile to a mechanical drive, disable indexing etc'. - They all create unnecessary writes.

I've had my SSD's for years, no problems at all, even if they are full 90% of the time.
Again I'm far from a light user and according to the SSD, I have still have over a decades worth of wear in it.

when i look at your setup and you have 3 x 7970,how does it effect your power supply if you have 3 cards running with everything else does it matter or is it easily handled

You're wrong:

If you are using an SLC SSD, sure there is nothing to worry about. But MLC...different story.

Doesn't affect my power supply at all.
Corsair PSU's are incredibly well built and will handle loads greater than they are advertised for.
Plus power consumption isn't a linear increase when you add more cards into your system due to GPU utilisation.

And another factor to take into account is idle/average power loads which can greatly impact your Power Supply's efficiency levels as a Power-Supply is at it's most efficient usually at around 50% load (Vary's from unit to unit.)

A... Blog is your credible source of wisdom? REALLY!?

Just turn the DX11 Depth of Feild effect off and you should be good for Metro 2033. That one effect will cut your framerate by 50-60%

Do the research before trying to be a smart ass. 

U dont need too powerful GPU or CPU these days to run games without hassle, 660ti is really good value card that will last you quite some time. You might even want to go a tad lower if ur on budget. Read some reviews and most importantly COMPARE BENCHMARK RESULTS, they'll give you a good indication how much better certain card is for certain games and such.

Skip SSD, very little space, still quite high price. You only save seconds not minutes from your loading times.

the memory speed is not really important, also the amount for gaming isn't important. 16gb of memory is way more than you need if youre mostly going to game on that comp, most games still run perfect only at 4gb or less, I'd recommend getting 8gb so you save a bit of money and have some extra memory for the CPU when u happen to multitask or do some light image/video editing. The average difference between memory speeds like 1333mhz and 1600mhz tends to be about 1-2 FPS, so it's really negligible gain. Pick the best value memory, there's not much difference between them.

Case doesnt matter what it is, as long as it can fit all your parts inside. Also DON'T SKIMP ON THE POWER SUPPLY!!! Read some reviews about them. Avoid the cheapo models which blow up inside the case and take other parts with them.

@Planetside 2 discussion, I play it. It's inferior to PS1 in everything else but the polish. Very lite on tactics or purpose, more like a neverending huge BF3 game. :( For people who are new to the series, it's propably quite a bit more impressive though...

Playing PS1 was like playing chess, playing PS2 is like playing checkers :D

Atleast the game is free and will get better in the future without any additional payments
