Want to upgrade from C2D to Core 2 Quad

hi friends,
i have system with specs are

C2D E7500 2.93ghz, 4gb ddr2 ram, xfx hd 5830 graphic card, intel DG41RQ mobo, cooler master GX 750 watt PSU.

i only want to upgrade processor from c2d to c2q.
please tell me which quad core will be best for my mobo, PSU and GPU?

i'm waiting for your ans... :??:

  1. This should be been posted in the CPU section since you would get more responses, but I'll help you out. The good new is your mobo can use any of the C2Q quad core CPUs as long as you have the correct BIOS version.


    I'm just going with Newegg since I like their search engine a lot and I've been buying from them since they first opened shop back in 2001... wow it's been 10 years. There are 4 C2Q CPUs available for sale from $240 to $350.


    The best bang for the buck would be the Q9550 for $300. The price is relatively high compared to other more current quad core CPUs that are more powerful. But due to low supply and low demand, the price is high.

  2. For that same $300 you can actually upgrade to a current quad core Sandy Bridge CPU that will give you better performance than simply upgrading the CPU to the Q9550.

    My recommendation is as follows.

    CPU: Intel i5-2400 = $190

    Motherboard: ASRock H61M-VS = $60 + $7 shipping

    RAM: Crucial Ballistix sport 4GB (2 x 2GB) 240-Pin DDR3 = $45

    Total price $302.

    The i5 is 3.1GHz (3.4GHz Turbo Boost) vs the Q9550's 2.83GHz. Therefore, it is a faster processor. Not only is it faster, but the Sandy Bridge family of i5 CPUs is around 10% - 15% better performing and the older Clarkdale family of i5 CPUs. Clarkdales performs about 15% better than the Yorkfield CPUs (like the Q9xxx series).

    Basically what this means is if the you compared an i5 and a Q9xxx CPU at the same clockspeed, the i5 CPU can process more instructions per clock cycle and thus, more powerful than the Q9xxx CPU.

    Turbo Boost is the ability for the CPU to "overclock" itself under high demand situations.

    The only issue with the i5-2400 and the Asrock motherboard is the limited overclocking potential. However, since you are using an Intel motherboard, I am sure you are not overclocking your current PC anyway.
  3. Lastly, here is a benchmark comparison between the Q9550 and the i5-2400.

    Note that for some benchmarks the higher score is better, for other benchmarks the lower score is better.

  4. I honestly wouldnt bother upgrading it, i would either overclock it (those cpu's overclock really well, should get it to 3.8ghz which would be plenty for any game), or totally switch platform. For the money it will cost you to get a 3ghz core 2 quad, you could just upgrade CPU and motherboard to something newer and better.
  5. thanks to all of you for helping me :) i have overclocked C2d e7500 @ 3.8 ghz..
    and XFX ati hd 5830 @ 850/1050
    for this i have changed intel dg41rq mobo to asus P5G41t-M LX mobo , and DDR2 2x2GB 800mhz to corsair XMS3 1x4gb DDR3 1600 Mhz and also installed hyper 212+ system cooler.... and now i'm saving for future... :(
