Need advice about my new rig

hello everybody ,

I'm going to buy a new pc in about 1 week.

I need some advice about the RAM, motherboard , and PSU

Allready got a bleu ray reader

This is what i must have ( no different parts in here)

---Antec 900 2 ultimate gaming case

---Sapphire hd 5850 X2 (crossfire)

---Amd phenom ii X4 965 black edition ( 125w edition or the higher one)

---8GB of ram ddr3(4x2gb) I don't know the difference between the different speeds and clock rates:s( need some advice here^^)
---Motherboard: one that will fit in everything

---Hard disk , 1TB storage (7200rpm)

---PSU that fits! ( i don't know how much W my computer will need)

What about the cooling, is this good enough? or do i need some more fans?

I can't use brands like: OCZ, CORSAIR, XFX , the guy that is going to order my pc doesn't support those..:s

I hope somebody can give me some advice, because i'm desperate..

  1. The 5850 specs are:
    500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)

    For twin 5850s I would recommend a 650W PSU with four PCIE 6pin connectors. Reliable power makes or breaks the system - if you get a crappy power supply you will at best have flakey lockups/performance problems and could possibly damage other components.

    For RAM, DDR3-1333 Cas7 should be fine. Unless you have a specific reason for 8GB RAM, 4GB would probably be plenty. 8 is slower and uses more power if you never use 4 anyway.
  2. for a mother board gigabyte 790x


    ETASIS ET750 True 750W

    SeaSonic S12E Bronze 650W 650W
