So I'm going to buy a new computer...

i know 2slots is enough for a basic raid setup but what i meant is that, vs onboard raid, which is free, its pretty much a waste of PCI-E slot because most cheap raid-card uses software raid and/or a hybrid of hardware and software raid.

... Obviously you would not buy that RAID card if you have onboard RAID. They're for people who want a cheap 2-disk hardware RAID system who don't have any kind of onboard RAID capability and who prefer hardware-based RAID.

The minimum for RAID 5 is actually 2 drives. It just becomes identical to a RAID 1 array. Because of how RAID 5 works, you can technically build an array with two drives.

+1, makes sense.

I've got a 5 disk external RAID which I put my animestuffs on.

what build do you have in mind anyway...
if you can wait till december(for the Christmas discount!), then you might be able to get some of the new arrivals, rumors says that the GTX6xx series's and the 6core sandybridge's ETA is around november.

Done building. Also installed a Corsair H70 for cooling purposes.
It works well, but a couple problems. Only 8Gb ram is recognized.
How do I overlclock my 970, I'm aware it's locked but you can still change the clocks I hear.

up the QPI and tune the cpu multiplier, either higher or lower.
firstly though find the max QPI the motherboard supports.
leave your core voltage on auto for now, lower the cpu multiplier to its minimum and crank the QPI up until it crashes, step 10mhz down and thats usually your stable BLCK.
if you get the max QPI, thats the time you start cranking the CPU multiplier up until it crashes, usually you`d get about 4-4.5 ghz on those i7s.
now this is the tricky part, lower the core voltage little by little after you got your desired overclock, use a benchmark or something to stress the cpu, once you get a crash, back it up by two nots, that would be your core voltage.
i suggest you settle on below 4.5ghz though, you could get it up to 5ghz with your liquid cooling if you tinkered it abit but thats just silly.

What is the best way to test for performance increase, and what app can I use to monitor temperatures?
What's safe, around 80 for GFX and 90 for processor?
This corsair H7 seems to be good though, CPU temps stable in the 50s during full load.
