Opinion on this build, all compatible

the innards look good - 2 things i'd change:

- PSU too powerful - all you need is a good 550W-600W one

- case is pretty cheap and flimsy for what you're building - i'd go with something like the Antec 300 Two (has front USB 3.0 too)

only thing is i plan to SLI dat *** when i have the money  

I am not much in favor of sli if a great single card will do the job.

Here is why:

a) How good do you really need to be?
A single GTX560 or 6870 can give you great performance at 1920 x 1200 in most games.

A single GTX560ti or 6950 will give you excellent performance at 1920 x 1200 in most games.
Even 2560 x 1600 will be good with lowered detail.
A single 7970 is about as good as it gets.

Only if you are looking at triple monitor gaming, then sli/cf will be needed.
Even that is now changing with triple monitor support on top end cards.

b) The costs for a single card are lower.
You require a less expensive motherboard; no need for sli/cf or multiple pci-e slots.
Even a ITX motherboard will do.

Your psu costs are less.
A GTX560ti needs a 450w psu, even a GTX580 only needs a 600w psu.
When you add another card to the mix, plan on adding 150-200w to your psu requirements.

Case cooling becomes more of an issue with dual cards.
That means a more expensive case with more and stronger fans.
You will also look at more noise.

c) Dual cards do not always render their half of the display in sync, causing microstuttering. It is an annoying effect.
The benefit of higher benchmark fps can be offset, particularly with lower tier cards.

d) dual card support is dependent on the driver. Not all games can benefit from dual cards.


e) cf/sli up front reduces your option to get another card for an upgrade. Not that I suggest you plan for that.
It will often be the case that replacing your current card with a newer gen card will offer a better upgrade path.

agreed ^ if you're investing in a video card at the ~$200 range, then it will be able to handle pretty much anything these days with 1 x monitor... and by the time it won't be able to handle your needs - it would be much wiser at that future time, to invest in whatever the latest generation ~$200 card is at the time, rather than SLI-ing your current one - with all the downfalls that come with 2 x cards (more power, more noise, less compatibility)

if you're going to use 2 x cards - best to do it from the start, if not - buy the best one you can afford now... then the best one you can afford in the future when in need of an upgrade
