Hi,
I'm planning to build me a new Home PCsystem.
I've made 3 different set-up's.

What system will give the best results concidered:
- I have a TFT-Display with 1920 by 1200 pixels (optimum resolution)
- useage of all sort of CAD programs (main use)
- useage of photoshop / Premiere
- and ofcource for some gaming (CryEngine2)

Set-Up 1
-Intel Quad Core Q9550 s775,2.83GHz,1333MHz,12MB,BOX
-Asus 775 P5Q Pro P45 DDR2 PCIe
-Sapphire ATI HD4870X2 2GB
-Corsair DDR2 1066MHz 4096MB XMS2-8500 Dominator (2*2GB)
-Western Digital 500GB Caviar GreenPower SATA II 16MB
-Sony Nec Optiarc DVD-Rom BLU-Ray BD2X/DVD8X

Set-UP 3
-AMD AM2 Phenom 64 II X4 940 quad-core 3,0GHz BOX
-Asus AM2 Crosshair II Formula N780 DDR2 3xPCIe

I'd say Set-up-2 is the best for your needs and wants. I'd however drop the gpu down to a gtx 280, or 4870x2. Then use the extra money and buy 3x2gb sticks of ram or even better try going for 6x2gbs of ram. I think for cad you want as much ram as you can get your hands onto.

On that setup you could also go with the Asus 1366 P6T verison and not the deluxe verison can also save you a few bucks. Could take that extra money and instead of getting the Western Digital 500gb green, go with WD Carviar black

I like Kubes' suggestions, but i would go with a GTX285 rather than a 280, or with the 4870x2. And definitely get at least 6gb ram.

Also, the Antec 300 isn't the largest case ever. If you are going to put a large graphics card I would suggest something a little more spacious.

And finally, are you overclocking? If so make sure to pick up an aftermarket cooler. If not, consider it.

Getting an Antec300, is this a big problem concidering a large graphics card?

And i'm not overclocking, should I?
(maybe in the future)

Things will be tight, and you may be limited to the placement of hard drives and wires because of the extended GPU length. This case has great cooling, is conservative looking, and is larger: http://www.newegg.com/Product/Product.aspx?Item=N82E16811119137
