Can you guys suggest cheaper, or better on some parts? like for example, is this motherboard easy to use n good at the same time? or like suggest cheaper case or something like that?

I have no experience with assembling all this but Ill try anyway. So do i only need to worry about overclocking processor n motherboard once the thing is all done and working?

Im planning to do a crossfire in the future when the price go down.
Is the intel i5 better or the AMD 955?

Since your budget is apparently huge, stick with the i5. You can overclock it to 3.2 GHz easily. Everything is fine as it is. Your PSU is capable of handling two 5870s in Crossfire, no problem with that.

The intel is better, however if you are concerned about price then go with the amd and spend the extra money you saved on getting yourself a 5970 then you will have a beast of a gaming rig....

When gaming the cpu doesnt get pushed as much as one would think. however the graphics card is your only limiting factor when gaming...
