Is this a good cpu for my computer and other questions

So im very new to working on computers. Ive replaced my video card and memory. Im looking to replace my cpu b/c I believe that it is holding me back. I have a 500w psu 6850videocard and 8g ram. My mother board is a M4A78LT-M LE

I was thinking about buying this AMD Phenom II X4 955 Deneb 3.2GHz Socket AM3 95W Quad-Core Desktop Processor HDX955WFK4DGM - OEM

I know that my old cpu Athlon II X2 255(3.1GHz) is 65w can my system take the new 95 watt cpu

Do i need a new heatsink fan/paste can you suggest one. Ive watched some youtube videos on how to install a cpu which are sometimes conflicting but i feel somewhat confident in installing one.

Lastly I also read that I need to change bios, How do I do that?
Thank you for any help. With this information the next computer I have, will hopefully be homebuilt. :)

  1. Specifications
    CPU AMD Socket AM3 ;Phenom™II /Athlon™II /Sempron™ 100 Series Processors
    Support 45nm CPU
    AMD Cool 'n' Quiet™ 2.0 Technology (by CPU type)
    Support CPU up to 95W
    *Refer to for the AMD CP

    Copied that from the motherboard specifications website. Also if your looking to get a new video card... a 650 watt Modular PSU might be a good idea. Though your 500 watt is still OK. But to answer your question yes the 955 will go in that mobo. But.... Might i suggest a Better Phenom. I tried the 955 in that Motherboard and it worked perfect. I still have the same motherboard in the box. But i currently have the Phenom II 980. If you want a little more performance without paying more. a 965 or 975 will be fine.


    Also your Motherboard is 6 core CPU ready. I would have gotten the 6 core at the time if i would have known what i would have been getting into. But the cheapest and most available 6 core is:

    I would get a 975 or 980. If your trying to last longer before making a MAJOR upgrade. But your chipset is getting older and older.....
  2. Thank you. In reference to my other questions, will I need a new fan/heatsink if I get the phenom 6core or the 980. As far as changing the bios how detailed is that process. Thank you for your time and any help.
  3. Bump
  4. The stock cooler that comes with the Phenom II x6 are decent coolers, but are very loud. You'd be happy with a CM Hyper 212+

    what is your BIOS version?
  5. BIOS Version/Date American Megatrends Inc. 0704, 6/11/2010

    SMBIOS Version 2.5

    Ok awesome dont care much about noise wasn't sure if it came with cooler. Thank you
  6. Also will this chip come with thermal paste if not does it matter which one I purchase. Thxs
  7. Which chip are you planning to buy?
    You current bios will support a Phenom II x4 945 & 960T. Both are good choices for gaming.
  8. I will put in whatever works best under 150. The guy up top suggested phenom 6core or the 980. The 2 you suggested seems to be on amazon but not newegg. If you think one of those are better for my comp then ill get the faster one. My computer has 500wpsu and a 5850 video card. Will that be enough psu to add a 125 chip in. Fan/heatsink enough. My case is a mid. [...] 6883229194
    Thanks again

    There isn't much performance difference between the 980 & 960T.
    With the 960T, you'd save some money, won't have to flash your BIOS & since its a 95W chip, you won't have to worry about having any support issues.
    I'd say save your money for your GPU upgrades
  10. K thank you so much. I meant 6850. Will try the 960T which im guessing is just plug and play.

    yes, you don't need touch anything in the bios. Just be careful with the cpu pins.
    Maybe this video can help you.
