Updated New system build

So Great
With this amazing rig I advise you to go with better ram
For 115$

and better for 120$

If you'll not go crossfire add 40$ more and get 8800GTS(512MB)

So in my opinion add one more 100$ and get almost a high end PC

Of course you still need HS+Fan For overclocking
Thermalright Ultra-120 Extreme
Scythe S-Flex SFF21F

By the way Get your Graphic card 8800GTS9 (512MB) and Muskin Ram ASAP cause they are running out of stock

truth be told the video card is the one thing that's gonna be subject to the most change, as the computer isn't gonna be built for another couple of month i'll probly put in a 4870 or 4870X2 or 3870 CF depending on the price and performances

also in the difference between the (5-4-4-12) memory and the (4-4-4-12) memory enough for the 25$ difference?

Not really unless you care about benchmarks. 1-3% best case real world. Newegg also has Corsair DHX 4-4-4-12 (for $104 after MIR http://www.newegg.com/Product/Product.aspx?Item=N82E168... ) It might be worth $14 to you but then again it might not.

This same rule applies to the motherboard IMO. You picked a high end motherboard.
What features does the RAMPAGE FORMULA have over the MAXIMUS FORMULA to be worth $25 more ?
What features do both have to be $50 or $75 more over P5E? Are they worth it?

rampage has the EPU which i've been unable to find anywhere else, but you do have a good point there, I'll probly go with 4-4-4-12 to squeaze all the juice possible

Speaking of which are there any other motherboards that can lower their power comsumption when the computer's not being used and also what would be a good harddrive? I'm thinking 2 or 3 way raid 0 with a combined max of 500 gigs...

Anyone got any ideas?

RAID 0 increases the chance of failure with each added drive. 2 x 320GB single platter would be the way to go.
I would recommend 1 WD6400AAKS for $110 from newegg(new drive, 2 platters, beats a $90 500GB drive in cost/gigabyte and performance).
If you are thinking of 3 drive RAID think about RAID 5 (data redundancy + performance increases).

What kind of applications do you use that make RAID 0's potential trouble worthwhile?
Ditch the Floppy Drive and get a Flash Card reader and a USB Flash Drive (thumb drive) instead.

P5E (X38 DDR2) has EPU as well (just so you know):

I reason why I want raid is because I really want my computer to boot up fast and since the harddrive whill probably be the slowest component, I might as well speed it up, also the reason why I want under 500Gigs (other than the waste it wouls as i've still never broken the 100 gigs mark) is that I'll backup on a 500Gig portable.

I actually forgot to look at how much space i'm using right now (90 gigs with pretty much all the crap in the world installed), that hard drive looks tempting but chances are quite good that I won't even reach 250 Gigs (I don't do video editing or anything really space consumming)


The floppy drive is also a card reader (I need to use floppies every now and then) and already got a 4gig flash drive (which by the time I get the computer will probly be a 8 or 16 gig one)

Asus Rampage Formula has overclocking potentials more than Maximus and P5E
Also If you can get CAS 4 memory for additional 25$ why to get CAS 5
Note that high end memories became unavailable and I believe manufactureres stopped making DDR2 and started DDR3, you can check Newegg and notice the invasion of DDR3
Hurry up and get your DDR2
