i5 2500k good for fsx?

Hey guys

I am about to buy an Intel i5 2500k. is it good with fsx. will it be smooth with ad don aircraft life the pmdg 737 with ad don scenery like fly Tampa. if i set some sliders to max settings will it still run smooth. i just want to get high fps in fsx with ad don scenery and aircraft.
please message ASAP :)

More about 2500k good fsx
  1. FSX is a ancient.
    It calls for a 1 GHz CPU, lol.

    And a 2500k is arguably the best(non hyperthreading) CPU. No bird poop under the IHS.
  2. Guys should i get Intel Core i5 3570K instead of i5 2500k
  3. We don't know why you need a great CPU for such FSX. Please explain more about what you want to do and what things you have.

    I need a great cpu because i want fsx to run smooth with addon scenery like fly Tampa and ad-don aircraft like the pmdg 737. this ad-dons need high fps to run smooth. which cpu do you think i should get.


    You have a i5 2500k. how is it with fsx. do you get high fps in addons like i listed above.
  5. according to this website i5 3570k is the second best for fsx??

    FSX might be old and call for a 1GHz CPU, but it's a beast of a program that can chew through resources like they aren't even there.

    3570k is Ivy Bridge version of the 2500k. A bit faster, and a bit better. I bought it over the 2500k.

    Funny, I know the 3570k is faster but I bought the 2500k instead for $20 cheaper than the 3570k. The 3570k is great though, and runs hot to prove it.
  9. I actually bought it for the PCIe 3.0 controller. Which is also why I bought a Z77 board over the X68. Upgrading motherboards is a PITA and with PCIe 3.0 out I didn't want to have to upgrade again later. In my mind it was worth $20. (and the ~7% increase in speed over the 2500K.)

    Okay thanks ill by the cpu you have.

    I have a question not related to his but here it is

    If i get the cpu you get i have to get a mother board with socket compatibility lga1155. My graphics card i have runs at x16, PCI-E. when I am looking at all mother boards i want to get it says "PCI Express 2.0 x16 @x4". what does the x4 mean.

    heres an example : http://www.newegg.ca/Product/Product.aspx?Item=N82E16813157297
  11. PCIe is a serial bus. By running multiple "lanes" together you can increase the bandwidth between the card and CPU. The "x4" means that even though its a normal 16x sized slot, there are only 4 lanes attached to it. This is bad for GPUs.

    That said that board does contain a normal PCIe 3.0 slot. So in this case that x4 slot shouldn't hold anything back. It's usually there in case you want to run a PhysX card or something like that.

    FYI, your "anyone" post is considered a bump and against forum rules. Please don't bump posts.

    So if i buy a mother boad that says PCI-E x16 @x4 will my gpu run at x16.
    sorry about bump. i am new.
  13. No. The card will run at full speed, but will get data from the CPU VERY slowly. This is bad. You'll be fine if you use the PCIe 3.0 slot however.

    what does it will get data from cpu slowly. if i were o get a PCI-E 3.0 its way to much the mother boards with that is like $300.

    What does this mean? The GPU has to get and send info to/from the CPU. If you only have x4 lanes of PCIe 2.0 this is slow for today's data hungry cards. Lower end cards will be fine, but bigger ones won't like it. They won't run to their full potential.

    Huh? You linked a PCIe 3.0 capable board. All it needs is an IB CPU. SB CPUs only have a PCIe 2.0 controller in them. Even if you get a SB CPU you can still use the PCIe 3.0 slot. It will just work at x16 2.0 speeds. (like that board you linked and the 2500k.)
  16. Graphics cards are very weak, relative the bandwidth of PCIe slots.

    If you dug up an old PCIe 1.1 board and dropped a Radeon 7970(or GTX 680) in a x8 slot you wouldn't notice any bottleneck. Perhaps the GPU generation after the next gen will be bottlenecked by 2.0 ...as I doubt Maxwell(nVidia) or Volcanic Islands(AMD) GPU's will be graphically strong enough to take advantage of 3.0, even in tri SLI or tri crossfire.

  17. idk, 80% of what a GTX680 can do... I knew PCIe 1.0 x16 wasn't bad, but I'm surprised at the x4. Nvidia won't even allow x16/x4 SLI, and on PCIe 1.0 (P35 chipset) AMD has horrible performance. I'd also like to see the 1080 graph.
  18. @ 4745455b

    They didn't test at 1920x1080, but did at 1200, 1050, 800
    here is the link to the article(performance summary page):

    http://www.techpowerup.com/reviews/Intel/Ivy_Bridge_PCI-Express_Scaling/23.html
  19. At 1200 (as close to 1080 as we can get though 1050 might be closer...) the GTX680 is down to 73%. 86% for the 7970. I'd still round it ~80%. Still way higher then what I thought for a x4 slot. And yet still enough that I wouldn't want to spend that much and get most of what it can do. Up to each buyer I guess.
