Gaming build. Looking for opinions!

[raize]

Alright so this is my first time building a PC. I'm fairly confident that I know what I'm getting myself into. Here's my build. Anything that you would recommend/change?

Case: Cooler Master CM690II Advanced
Mobo: Gigabyte GA-P55A-UD3 LGA 1156 Intel P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
GPU: Sapphire Radeon HD 5870 (going to get another later on and Crossfire them)
CPU: Intel Core i5-750 1156
RAM: G.SKILL PI 4GB (2x2) 240-pin DDR3 (Is 4GB of RAM enough? I do some multitasking (video recording/editing, photoshop, web browsing, etc.) and I'm not sure how much RAM would be viable.
PSU: Antec EarthWatts 650W (Will this be enough? Especially when I Crossfire later on?)
HDD: Samsung Spinpoint F3 1TB
Monitor: Asus VH236H 2ms 23" LCD 1080p
CD/DVD: Any recommendations?
Fans: 2x 120mm Antec case fans (The case only comes with 1 front, 1 top and 1 rear. I'd like to have some side ventilation as well)
Heatsink: Cooler Master Hyper 212+ (The i5-750 stock heatsink is a joke apparently)
OS: Windows 7 Home Premium 64-bit (Is it ok to get the System Builders version? I'm assuming there's no difference between the OEM and retail version other than the price tag)

So my biggest questions are...
1) Will everything here work together? I've done a lot of research and it seems fine.
2)Will my PSU put out enough power whenever I decide to Crossfire? I might not even Crossfire. Most of the games that I play aren't incredibly graphic intensive (WoW, TF2, and upcoming Diablo 3) but I might play some BF3 when it comes out. Still undecided.
3) Will everything fit? That heatsink is pretty damn huge.
4) Am I missing anything? Aside from the usual mouse/keyboard/speakers. I've already got that covered. I'm assuming everything here comes with everything that's necessary to get this thing running. I don't want to have to make a trip to Best Buy because I'm missing a cable or something.
And of course...
5) Is there anything you would change? Why? I'm open to any and all suggestions. Also, I hear Crossfiring leads to a lot of microstutter.

Please and thank you

id go for the corsair TX 750 because your going to upgrade later for 2 gfx cards so the higher power will be better plus it as all the connections.

4gb ram should be enough and run perfect. 8gb is just over kill if you ask me.

First off the i5-760 is only 174.99 ATM @ newegg.com So go with that CPU

The mobo only does Has 1 16 X PCI-E , not a good xfire mobo go with http://www.newegg.com/Product/Product.aspx?Item=N82E16813131621

8 gigs of ram would be good for your /editing and photoshop needs http://www.newegg.com/Product/Product.aspx?Item=N82E16820231329 no need for very fast ram, if your not trying to OC to the max.

PSU the Corsair 750 is a good deal atm for 69.99 with the MIR http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006

Why not get the 6870 GPU ? improved architecture over hd5800
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102909

The OS a OME ver can only be used for one PC it will be linked to the mobo.


A little read me on GPUs http://www.anandtech.com/show/3987/amds-radeon-6870-6850-renewing-competition-in-the-midrange-market/21

i would wait for the new OFFICIAL successor to the 5870...theyre not the 6870 contrary to the naming

the real successors will be within the 69xx series...probably 6970...so you should wait for those...

I'd switch the build and make it a SLI unit and not crossfire so that calls for a change in motherboard. GTX470's are on sale now..
i like paring intel with nVidia more than intel with ATi. my opinion..

The i5 and RAM is cool, if still a student then you can get the Win7 through Microsoft student program.
the Spinpoint F3 1TB like you have is on sale for the same as the 500GB so good call.
add SSD - OCZ Technology 60 GB Vertex 2 Series SATA II

I've got friends who swear by ATi, so I think I'm going to stick with it. I appreciate it though.

I have checked out the student program, but they only offer Win7 upgrades, and since this is a fresh build I don't have Vista or XP on it so there is nothing to upgrade.

I was also going to add a SSD, but I'm already limiting myself on the money at the moment. I'll do that later.

One more question, since the HDD I'm buying is a bare drive, it doesn't come with a data cable, correct? Will this suffice? http://www.newegg.com/Product/Product.aspx?Item=N82E16812226004 And I'm assuming I don't need any screws, because the drive bays have trays in them to mount the drives.

Another question.

What is the ideal setup for fans? I will have the 140mm on the front, another 140mm on the top, a 120mm on the rear and 2 (120 or 140s, haven't decided) on the left side. I've read some that recommend front/sides intake, rear/top exhaust while others say only front intake while sides/rear/top exhaust. I'm assuming you can flip fans backwards or forwards to determine which way they push/pull air as well.
