Your not supposed to mix Ram even from the same manufacturer.
So if you have 8GB and want 16GB it's normal to sell the 8GB
and buy 16GB The sticks have a version number on the
label, but even that doesn't guarantee that they are identical.
Revisions are usually drastic and often involve using chips
from another manufacturer.

This list is out of date but it shows how often
manufacturers change chips. They also change other
components and the circuit diagram.

It also seems better to only use 2 slots in a 4 slot machine.
The memory forums are riddled with posts about people getting
BSOD's with 4 slots filled.

More ram seems to bring problems. On previous systems I had
4GB and never had any problems.... now with 8GB I've had errors
copying a large group of files once and burnt my first DVD
coaster in about 10 years

Intel i7 internal graphics only (no card) running a load
of Adobe stuff and 11 No. 1080p videos.......

It looks like at least a GeForce GT 640 would be needed to
show any improvement, but that means a big fan blocking off
some PCIE slots which can be used for other things such as
an IDE Card.

I still just use the internal graphics which make use of some Intel software.
It seems fast enough. I might try a card later for video.

USB3 is essential on a new board. Some USB3 flash drives can
read at over 200MB/s.

One tip about external backup drives.... try to standardise on the
power supply so that you don't need a different one for every
drive. Mine are mostly 12V 3 amp circular plus +ve centre.

For Elements 12 you don't need too high a spec.

A lot depends on whether you want to overclock or not.
Personally I prefer not to and always use Intel. Are
AMD still being developed?

For editing Intels are faster than AMD's I bought an i5 4440 after
looking at this chart...... Most Intels were within
25-30 secs so very little return for more money and
twice as fast as an AMD - A10 6800K

Beware of CPU and memory benchmarks.... they mean little in the
real world.

This page tests some CPU's ....

A 64bit OS is probably an advantage. Memory speed isn't
too important as long as it's 1333MHz or higher. I use
8GB which seems OK. I can't see any difference running
at 1333 or 1866 which is the XMS profile.

Gigabyte boards seem to have a slight edge on the Asus boards
at present and it depends on what you need I needed rear
eSATA ports so I went with an older board Gigabyte z87x-ud4h

Sigma service sounds very good

Nano-Universe produced a slightly better looking bag for the
GR unfortunately it looks to be made from denim.....

You might get away with it. The best thing to do is make sure
it's as clean as possible. About the best lens cleaner you can
get is ROR available from many sources, but the distributor
seems the cheapest and they are an excellent professional firm
to deal with.

I regret not buying some double (back to back) K lens caps
from them when they had them in stock. They let you store
two lenses together. I suppose I could try glue

Have a look at this review....

Not very good considering it's Jessops and the sound is very
weak.

On the same page was this very good review of the the K-50
some of which will also apply to the K-S1 particularly about
the pentaprism.

He also does a good review of the WG Series...
