Crysis homebuilt system components?

Basically:

1. Basically any recent motherboard will work with any video card these days; it's only when you get into multi-card crossfire or SLI setups that you have to worry.

1a. I would not necessarily worry about dual graphics cards. When starting from scratch, if you can find a good single card that has comparable performance to a dual-card setup, it's almost always going to be lower in price and give you fewer headaches than crossfiring. But basically any motherboard with two PCIe x16 slots can support it - just make sure that a) If you get Nvidia cards, it says it supports SLI, or if you get ATI cards it supports Crossfire, and b) You want one that says at least x16/x8 or x8/x8 with two cards -- STAY AWAY from anything that says x16/x4; it will mess up your performance big-time.

2. You don't really NEED a solid-state drive, though they will speed up load times noticeably. I'm still perfectly happy with a 7200 rpm Samsung Spinpoint, Seagate Barracuda, or 10,000 rpm WD Velociraptor. Personally, I don't think SSDs are there yet in terms of price unless you're building an extreme high-end rig; in another several months or a year they might be realistic for normal people.

3. If you're using DDR3, to keep things simple I would just get something that uses 1.5V. That makes it pretty certain that you can just plug-and-play. A lot of higher-performance RAM uses 1.65V and up, but you'll have to set that manually in your BIOS. Don't get anything above 1.65V if you're using an Intel i5/i7 CPU, because you can damage the CPU that way.

Basically, if you're looking to be semi budget-conscious, I'd use roughly this for the core of my system:

- Socket AM3 motherboard ($50 and up, $80+ for a good one, $90+ for one with crossfire)
- AMD Phenom II x4 quad-core CPU ($150-$180)
- 4GB DDR3 RAM (approx. $100)
- HD 5850 or HD 5870 video card ($300-$400)
- Spinpoint 500GB hard drive ($50)

If you decide to go to the Intel equivalent (1366 motherboard/i7 CPU) expect to pay about $200 more for a slight boost in performance ... if you go to the Nvidia equivalent on the video card (GTX 470/480) expect to add on another $60-$100 for no boost in performance.

Thankyou very much for the help

ALSO WHAT POWER SUPPLY SHOULD I GET AS I DONT WANT TO GET IT WRONG....... ARE ALL THESE PARTS COMPATIBLE?

Also do you have to have an ssd in a PC?

And will the 5870 graphics card be compatible with this system?
Will I eventually be able to run the cards in dual? (is the motherboard good enough)

no you do not have to have an SSD in a PC

I really dont know if you can crossfre with nvidia chipsets

and ill be assuming (the links dont work) youll be buying a phenom ii x4 945, the processor is ok for gaming and maybe a mild overclock

I would recommend getting an AMD chipset if you want to crossfire \

or get a Nvidia Geforce graphics card ( I dont recommend this choice but its ur build)

It looks like that motherboard supports SLI but not Crossfire. So a single 5870 will work (any single card will work in any motherboard, remember), but dual 5870s will not work. If it only supports SLI, you can only use Nvidia cards in dual.

None of your links work, but I saw a graphics card for $549.99, which the only match for is a 5870 with 2GB of RAM. You do not need 2GB or RAM on a single video card ever; you're just wasting your money unless you have an insane video setup in place. The only place normal people notice a difference with the amount of video card RAM is the 512MB-1GB boundary - 512MB is plenty to run at max on monitors up to 1600 pixels wide, but at resolutions above that, you'll see 512MB sstart to struggle but 1GB do better. You do not need 2GB unless you're planning on running a 40" monitor or something. Save the $150 and get a standard 1GB version of the 5870, which ought to be more like $400.

Most of your links didn't work...

Here's a combo that is the same MOBO and PROCESSOR you selected but at a combo price of $20.00 less.

SSD's aren't necessary but certainly nice to have if you can afford one. Maybe save up for a while and get one of the smaller capacity SSD drives (64 - 80 GB) just for your OS and a few games. It'll make a big difference in system response.
