Building high end pc need help

Hi, I wanna build a high end gaming pc I allready have 295 gtx on my old pc I am looking to make a new build.

the parts I am thinking of buying:
1-Intel i7 975 ex or i7 920
2-Rampage II Extreme
3- 6 gb x3 DDr3 1600 mhz or 1800 mhz or 2133 mhz whichever I can find but please suggest
4- 10,000 rpm 300 gb
5-1000 w psu
6- v8 cooler or thermal 14 copper 1 whatever I can find
7- add another xfx 295 gtx run them in quad I allready get some miro stutter in some games so I am used to it and dosent bother me lol.
8- case depends on what I find in my area probably gigabyte or something.

I am looking into overclocking the 975 to 4.1ghz and I really want the highest fps in most current games if you suggest any changes to the cpu or otherr components please do I allways ask ppl about the i7920 but they give the same answer its cheap and u can get it 4.0 well some ppl reach 3.5-6 my question is not the money but if the extreme will gain more fps in most demanding games id go for it if it will help.
If a 920 can match it overclocked in games performance wise id go with 920 but am not trying to save money here I really want to build a gd pc .

things I don't plan to get is solid state. too expensive here

aswome atleast the cpu mestery got cleared But I allready Have a 295 gtx too late >.< I can quad them I will buy 300 when there out by summer next year so np but in the mean time I don't wanna sell the gtx 295 will be so hard and I only had it for 1 week

i7 975 definitely overclocks better and easier than i7 920 due to higher binning and unlocked multiplier. For gaming though the i7 975 isnt really worth the extra expense.
