I'm guessing this question has become quite annoying by now, but I'll still give it a shot 
Im putting together a computer. I have put together a list of components. Thought I am not sure about the motherboard (and I'm not 100% sure whether the components fit)
I apologise, this page I'm ordering from is Estonian.
These are the components
Do i need 990 or can I (in this case) replace it with a cheaper 970.
List of 970's on the 1a page:
Motherboards on the 1a page
I will be overclocking the CPU.
I don't really need the SLI since if by any chance in the future I want a double Graphics card I will keep 280x and crossfire it with another ATI prolly.
Please comment the overall selection of parts and maybe recommend something
(and how can I tell if my parts are 64bit or 32?)
Thank you!
