Hello, I am fairly new to building PC's, and in fact, I've never built one from the ground up. However, I wish to do so soon. I plan on using SLI and RAID0 in this build. Could someone check the compatibility of the following parts? Also, could someone tell me if the motherboard supports RAID, or if I need a control card? I've been told yes and no.
It appears that that the build is compatible, I can’t pull up the links but just make sure the memory that you have selected is 1.5v. Using memory that is rated at 1.65v can damage the processor and void your warranty. Other than that I don’t see any issues.
If you are planning on overclocking the Intel® Core™ i7-2600K then you are going to want to pick up a good 3rd party cooler. Now the Intel Core i7-2600K is a fairly cool running processor so you don't need to get a water cooler unless you are planning to do some extreme overclock on it.
The Asus P8Z68-V Pro does support RAID, you will want to set it up in the Bios before you load your OS but it is fairly simple to do.
GTX 56ti SLI pulls a max gaming load of 375W. This means your average gaming load will be under 500W, and you will NEVER exceed 600W. This makes a good 750W PSU your ideal, as it will be more efficient when you need it to be.
