  1. From the GA's supported DDR list the G.Skill (F3-12800CL7D-4GBECO) 4GB is good choice for 32-bit OS and fine for 64-bit OS based upon you needs listed above. Also, when you choose DDR from GA's supported list you can use XMP in the BIOS. XMP makes it super easy to configure your DDR precisely by setting your DDR automatically.
    Same DDR List (double checked & confirmed):
    REV 2.1 -
    REV 2.0 -

    The 1600 G.Skill 4GB (2 x 2GB) $98 USD - XMP is supported P/N F3-12800CL7D-4GBECO and offers good speed, anything faster won't gain you much -

    Regarding, a choice between ATI and nVida then I would choose the 460 or 465. Also, while "I prefer" EVGA, Zotac is worth a consideration and both offer a "Lifetime Warranty" on their GPUs:
    EVGA {note P/Ns not all GPUs have lifetime} -
    Zotac -
    Tom's Reviews of nVida 460 -,2714-10.html

    Regarding, and SSD + HDD {HHD ~ a/k/a H-HDD}- you might want to look into the newer Hybrid drivers. I really like the idea and makes for a cleaner environment without the need of moving Documents, Music, etc folders, installing, etc... -

    A note about HHD: people can't wrap their minds around and or ignore the fact that only 32 GB of the most used apps and OS will be migrated on to the SSD portion of the drive. Meaning, synthetic tests are all "new data" to the HHD and won't be loaded onto the SSD portion so the tests will always show ~ HDD performance. Then the same people are all excited because their OS + Apps loads ~ speeds as an SSD. Duh!?
  2. Hi there,

    Well, first you have to decide the motherboard/CPU combination you want to use. Both of your choices are great. Then make sure they are compatible, from the MB web page (they are compatible.)

    Then choose your RAM from their already tested and compatible chart. Lots of folks don't do that, or try what they have, and more often than not have problems. Here are their RAM specs:

    1. 4 x 1.5V DDR3 DIMM sockets supporting up to 16 GB of system memory (Will handle up to 16 GB with Windows 7 64 bit) (Need max 4 GB if Windows XP, Vista, Win-7 32bit).
    2. Dual channel memory architecture
    3. Support for DDR3 1866(OC)(Note 2)/1333/1066 MHz memory modules

    If you are going to purchase 2 sticks or 4 sticks, buy them in a matched set so they have been tested by the manufacturer to play well together

    And here is their RAM compatibility URL:

    Also check out and choose a CPU heat sink for your CPU that doesn't fit out into the RAM chip "space" so all slots will be available and will function, even if right now you decide to only choose 2 initially.

    A nice SSD for the OS is a great choice, and say a WD 1 TB SATA HDD Black for performance data storage. (been on sale ~ $80)

    I have an XFX 5850 video card and it is very nice. Fits the width of an ATX board. Have had no experience wit the 460 but think it is longer. Check the physical specs to make sure it will comfortably fit in your case.

    Then add up the power requirements for your rig, and add another 50% in choosing your power supply. Always check the cables or modular plugs to make sure the PSU has the cabling you will need. A 750 W or greater PSU would be sufficient. The larger cards like the 5850 requires 2 separate PIC-E 6 plugs.

    Half the fun is choosing the components you want, and know they will work together
  3. Thanks for the replys guys..guess ill go with the motherboard and the ram and now i have some more reading to do. I didnt know about these hybird drives but it sure sounds interesting. Still cant decide on the vid card. The 460 would save me a few bucks, didnt look at the prices on the 465 but will do so. Now I know that they will work ok with the amd mombo. the 5850 i know is a great card but may be over kill for me as I dont play much games other then wow.
    The amd 955be should be some inprovement over my older core 2 duo
    and this motherboard can use the new 6 core, but dont know why i'd need that at this point in time. It does give me some future path for upgrading and maybe will be able to use the new bulldozer chip when it comes out. I belive i'm on the right path here and will have a platform that will serve me well for a few years..thanks again

    In regards to "future path," where most people make "mistakes" is not investing in a good-solid PSU and Case which can be reused and offer a lot more "future" than CPU, GPU, DDR, HDD/SSD which have a more limited shelf life. If for some reason in the future you need more speed you can always SLI the GPU whereas in the past you had to file-13 the old GPU.

    Also, in general, 4-6+ core CPUs are theoretically nice, but most games and applications are limited to 2-cores so the speed and architecture of CPU is a relevant consideration.

    Good Luck!
  5. Don't buy low voltage ram 1.35v for an AMD board it's a pita unless it's an 890 chipset or you really like playing with bios settings to get your ram to run at specified speeds.
    I would buy this 1600Mhz CL7 ram.
    Mushkin Enhanced Blackline 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop -$94.99
    Buying 1.35v ram and having to up it to 1.5v kinda defeats the purpose of the lowvo.
  6. If OP OC up the voltage to 1.4v and you'll be fine. The G.skill is certified for this MOBO.
