CPU for ATI 4850


I had bought ATI 4850 GPU couple of years back. Sadly then, I had Intel Pentium D, 2.8 Ghz, which actually never allowed my GPU to deliver to its true potential.
It's a bit down the lane, but can you help me find a CPU today that can be good enough for that GPU. I aim to get just the right CPU+Mobo for the GPU.

I had personally pinned down i2500K / AMD 1090T. But my knowledge of recent past is not that good about the performance and AMD vs Intel for ATI Radean. My budget would be not more than $200 for the CPU + Mobo, lower the better.

Objective: Get good CPU+Mobo for ATI 4580, which delivers its true potential for gaming, at minimmum cost. Or any better alternative you may suggest.

  1. I see what you are saying.The Radeon HD 4850 was quite a nice graphics card back in the heyday of 2008.So what you are trying to do is have a balanced machine good for gaming yet you realize that the HD 4850 is not considered a high end graphics card today but still somewhat potent and useful.
    You are trying to save some money.

    I think that a good match would be anywhere between a AMD Athlon II X3 CPU like the Athlon II X3 455 (or any Athlon II X3 for that matter) up to a Sandybridge Intel Core i3-2100 (fairly potent yet inexpensive).

    If you go too high in price for a CPU you might as well get a better graphics card.Either that or just consider using the HD 4850 temporarily until you can afford a better graphics card.

  2. The 4850 Does not need an i5 or 6 core Cpu to get the most from it an Athlon x3 with a cheap board is fine. How about:
    Athlon x3 445 $75 http://www.newegg.com/Product/Product.aspx?Item=N82E16819103872
    Cheap motherboard $40 http://www.newegg.com/Product/Product.aspx?Item=N82E16813157202
    I have used these components with a 4870 and it runs great.
  3. I myself would now tend to avoid getting a AM2+ motherboard if you decide to get a AM3 type CPU like the Athlon II X3.Why? Because DDR3 memory is so much less expensive than older DDR2 memory and performs better.You could even consider getting a inexpensive AM3+ motherboard too if you desire a future (AM3+ Bulldozer) CPU upgrade.
    A AM3 motherboard would be alright too if you stick with AM3 CPU's like the Athlon II X3's
    However there are LGA 1155 motherboards for that Sandybridge Intel Core i3-2100 CPU at around the $70 price point so you could keep the CPU+ Motherboard costs under $200 if you want.
  4. The board I recommended takes DDR3 Memory or DDR2 memory
  5. My bad you're right it can take DDR 3 according to Asrock's website under the QV List of memory.
  6. Its worth checking out the new Pentium G8XX series as well but the Athlon build should be cheaper.
  7. OK,

    Great advice! It basically brings me down to ask you:

    --> Is it advisable, as also suggested by jj463rd, that since I am upgrading I buy a good CPU and wait a bit to update the GPU later, when I can afford it. Since, I wouldn't like to update the CPU again then. That would make the decision right now a "bit future safe" as well.


    --> Buy the combination suggested by simon12 and if requried do complete upgrade few years down the line?

    Just to add one more missing information: My current motherboard is Asus P5KPLM-CM.

    Also, is it true that AMD CPUs are better companion for ATI Radean then Intel, esp when it comes to gaming? I see that as a reason you suggesting the AMD series, apart for them being definitely cheaper :) I have always landed up confused when making a choice between AMD and Intel!

    @jj463rd: Thanks for understanding my situation so accurately, and nice article links!

    @simon12: Since, you have used similar series GPU series and I presume, you have upgraded by now, so your advice also is really valuable.

    Thanks for taking the time out :)!
  8. You could just get a better motherboard that supports AM3+ CPUs and upgrade to a bulldozer CPU down the line when they are released something like this http://www.newegg.com/Product/Product.aspx?Item=N82E16813157262 $104.99 or get a 1155 board and a 2500K now and it should be good for any graphics card that comes up in the next year or so something like:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813157229 149.99
    http://www.newegg.com/Product/Product.aspx?Item=N82E16819115072 219.99
    All the boards I suggested support Crossfire and SLi if you don't need that there are cheaper options.
  9. You should have mentioned before your current LGA 775 motherboard (Asus P5KPLM-CM)
    which will take more potent Core 2 Duo and Core 2 Quad CPU's as a possible upgrade.Although now there are better CPU's on the market.
    Getting a inexpensive Core 2 Duo CPU like a Intel Core2 Duo E7500 Wolfdale 2.93GHz 3MB L2 Cache LGA 775 65W Dual-Core Processor just as an upgrade to your current board would be an alternative however the price on this CPU seems kinda high right now.



    "Also, is it true that AMD CPUs are better companion for ATI Radean then Intel, esp when it comes to gaming? I see that as a reason you suggesting the AMD series, apart for them being definitely cheaper I have always landed up confused when making a choice between AMD and Intel!"

    No,either AMD or Intel CPU platforms are fine with your graphics card.

    The $125 Intel Core i3 2100 performs about 50% better in gaming than a AMD Athlon II X3 450 (which is slightly faster than a 445) as seen in these benchmarks.


    You can also compare other CPU's as well

    Here are some under $75 LGA 1155 motherboards for it which together would total
    $200 for the CPU+Motherboard.


    Still simon12 did list a CPU and Motherboard so inexpensive that with $200 you would easily be able to include the RAM in it and perhaps even a inexpensive DVD Burner all for under $200.Again though the Intel i3-2100 will get about 50% better frame rates in gaming according to the games under Anandtech's benches.

    The i5-2500K is about a perfect gaming CPU right now but by itself the CPU is over $200 (which would put you over your $200 budget).There is a deal right now that ends today for the i5-2500K with $15 off of its $220 price at newegg.

    Still I'd opt for the i3-2100
