The specific concerns I have:
Is the amount of RAM needed. Is 4GB enough? How about the hertz, is 1600 much better?
Also the SSD HDD, is that going to do a lot for my system? It´s so small I wont be able to install many games on it anyway.
Is the 2500K and the 570 a good match?
And lastly, do you spot any glaring bottle-necks? Is there somewhere I can save money and still get decent performance?
First time I have seen Icelandic on the forum.
Triple channel kits are designed for LGA 1366 system's and you should go with 4GB (enough for most applications) or 8gb dual channel kits! The speed of the memory is not a huge issue usually the slower ram has tighter timings (latencies). If you are going with the 2500K then I would though go with 1600MHz ram.
GTX570 and I5 2500K are a great match.
Looks like a good system over all but what PSU are you using?
4GB is enough if you game, if you want more go for eight.
1155 is dual channel, so with 6, one stick of RAM will run in single channel and hinder performance.
Your board only doesn't SLI though, can you find Z68 boards? Something like the GIGABYTE GA-Z68A-D3H-B3 would be great.
Also, 120GB is plenty of space for a SSD, 60/64 is enough for windows with ~30GB leftover. IMO, if you can find Z68, get a caching Intel 311 to use SRT. You can save quite a bit while not losing too much performance.
Other than that, your build is actually pretty balanced. Make sure its the K version though and get a quality PSU.
The coolmax will do but is not on the recommended list. (what store are you buying from no language barrier)
The Z68 board suggested by Timop would be a great choice.
Are you planning a storage HDD along with the SSD?
Store is Tölvutek. They were the cheapest for a long time but now everyones prices are pretty much the same. I still maintain my loyalty though. They´ve always treated me fairly. Got a suggestion for something else?
You can carry on using the Coolmax although not recommended. It has passive pfc (rauði rofin til að velja á milli 115 og 230volt spennu) which is inefficient compared to newer 80+ and higher certified PSU's. The PSU is the single most important piece of equipment and when a low quality one dies it can take other more expensive components with it.
