  1. what other parts have you selected... with the limited info provided probably something like this
  2. ah sorry i shoulda given better info. well im going with the amd x4 black edition, radeon hd 5850, 2tb harddrive, 1200watt power supply. keep in mind that i will be adding a second 5850 with in a few months. i will eventually add a 6core cpu, woulda done it now but i want to wait and see what happens with price in sevral months either way its an am3 slot so no biggie. i will be adding a solid state drive later also. i dont think my rom drive, tower and heatsink really change anything about the memory and cooling wont be an issue.
  3. the mem above will be sufficient, though your psu is a bit excessive IMHO

    1- This G.Skill Ripjaws 4GB (2x2GB) 1333 are very good and are a very good option for u.

    2- The PSU is overkill for your rig, this are the power requirements for your GPU.

    ATI Radeon™ HD 5850 System Requirements

    * PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
    * 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)
    * Certified power supplies are recommended. Refer to for a list of Certified products
    * Minimum 1GB of system memory
    * Installation software requires CD-ROM drive
    * DVD playback requires DVD drive
    * Blu-ray™ playback requires Blu-ray drive
    * For an ATI CrossFireX™ system, a second ATI Radeon™ HD 5850 graphics card, an ATI CrossFireX Ready motherboard and one ATI CrossFireX Bridge Interconnect cable per graphics card (included) are required

    The recomended PSU is for the entire system, with this Antec 650W is enough for your rig and the future Crossfire and CPU upgrade that u want.

    3- IMO the mobo is very good, but if u want OC the rig, u can wait two weeks for the Gigabyte 890FXA-UD5 that is a better mobo for OC.

  6. i went to one of the power usage calculator and again me being the noob that i am did the best i could and after i set up everything i was going to have it came out to 1100watts or so...i looked up prebuilt systems similer to what i wanted to do and they used 650 to 800 power supplies so glad to hear you guys are knocking some sense into me. thanks again for the feedback.
  7. Any time, that's why we are here. Don't forget that the PSU must bet from a good manufacturer like Antec, PC Power and cooling or Coolermaster.
