    AMD Upgrade For Hp p6687c Desktop PC

    My Pc is a Hp Pavilion model p6687c. It has the AMD Phenom IIX4 840T 2.9Ghz CPU. 8 GB of ram with 64 bit Win7 Home Premium. I'm looking into and upgrade or two. The Hp site says I can upgrade to the AMD Phenom IIX6 10xxT sixcore (Thuban core) CPU. This sounds good to me. Since my PC is 64 bit I can max the ram out at 16GB. This also sounds good! Now I'd love to ditch the onboard graphic. The Hp site says I can run a PCI Express 16X video card. All of this now sounds great to me...LOL Remember I'll old and stupid. Here is where the problem is. This PC only has a 250 watt PSU. Most any PCI Express card worth having requires something around a 400 watts out of the PSU. I guess I'll have to upgrade the PSU too. There is nothing offered as and upgrade for my 250 watt PSU on the Hp site not that I'd buy any of this stuff from them anyway. My hope is that Hp-Compaq hasn't done anything stupid with the pinout of their 250 watt PSU. I'll just buy a 800 watt PSU. My plan is to upgrade my PC with all the above listed goodies. If it works then I'll upgrade my wife's PC too. She has the exact same PC as I do.

    A quadcore and 8GB is more than enough, even for gaming.
    I'd replace the powersupply and get a decent mid-range graphics card. Viola.. You got yourself a gaming capable computer (and I'm talking games from the last couple years in at least medium settings)

    800W would be total overkill. A good ~450W unit would be fine.

    No idea what your budget is, but this is what I'd suggest

    The graphics card.. well.. depends strongly on your budget.

    Just a suggestion. I'm kinda curious what others would put together instead.

      I would suggest the same parts that Scenic linked from Newegg.com.

      In addition to Scenic's suggestions, if you're looking for a CPU upgrade, unfortunately not many places really stock regular AMD AM3 processors anymore after the release of the AM3+ Bulldozer FX-series processors. The best Phenom II X6 that I could find (being in stock) was the 1055T 2.8GHz at NCIX US for $149.98: http://us.ncix.com/products/?sku=520...anufacture=AMD

        OK I gave myself brain damage trying to figure out the AMD family of newer CPU's. My last AMD that I used and loved was I think the AMD 450 K6/2. Had a fast AMD T Bird? something in a home built. Didn't like it because it didn't have the SSE instruction set. I couldn't stream Netflix with it. Now on to what I have now. This would be the AMD Phenon IIx4 840T 2.9 Ghz. If I understand it right. This CPU is actually a AMD Phenom IIx6 10xxT sixcore Thuban that didn't pass tech. Its crippled by have two of its cores disabled to make it into a AMD Phenon II 840T.
        Now on the upgrade I think I'll leave the CPU alone. My PC has enough balls with its four core. I'm going to do the PCI Express 16X video card and a better PSU. I don't game but my wife does. She will get a better Card than I buy for myself.

          With those CPUs that have cores disabled, you can enable them on some motherboards if the BIOS supports it, but it's a gamble if they'll actually work OK or not.

            That is just it. There is no way of knowing if my CPU was crippled because it failed Tech as a six core or if it was fine and was crippled because they needed more 840T four core CPUs. It makes more sense to make all of the family from six core CPU's and then cripple them to make the four core CPUs. It would cost them less in the long run.

              No harm in trying it out, though, if you try and they are unstable then just disable core unlock again.
