How much of a performance difference 2x8800GT to Geforce 460 on my sys

I have the opportunity to pick up a Geforce 460 for $120. I was wondering how much of a performance difference I could expect to see on my system upgrading from 2x 8800 GT running SLI. I'm thinking about this purely in terms of gaming performance.

System: Dell XPS 630i
Mobo: nForce 650i SLI
CPU: Q6600 overclocked at 3.150 for each core
Memory: 2x 2GB Corsair DDR2
PSU: 750W
Current GPUs: 2x 8800GT 512MB
Potential GPU: 1x EVGA Superclocked Geforce 460 1GB
Display: runs at 1440x900

Side question: If I do upgrade to the 460 am I able to use one of the 8800GTs as a PhysX card?

  1. You should have no issues with using an 8800GT as a PhysX card but as for whether it'll be a worthy upgrade or not? I don't know, two yes but just one...
  2. Best answer
    At stock it will be a slight upgrade but when OCed it will pull away nicely. Honestly though at your resolution the performance difference probably wont be all that noticeable as 2 8800GTs should already be very good. It will however remove any SLI scaling/compatibility issues, give you DX11 compatibility and use much, much less power. The GTX 460 uses 50w+ less under load and over 5 times less power at idle. You will be able to use the 8800GT as a Physx card which isn't a big deal imo but you can also use the slot for another GTX 460 at some point if you upgrade your monitor.
    Hell, even if you don't want to use the card for $120 you can always just put it on Ebay and make $100.
  3. The only reason I'm not thinking about two 460s running SLI is that my mobo only does 1x PCIe 16 or 2x PCIe 8. It won't do 2x PCIe 16 so I'm worried I'd lose basically all the benefit to scaling issues. Especially since this is a PCIe 1.0 mobo.
  4. I don't think the x8 will be that big of an issue but you certainly do not need more than 1 GTX 460 with a 1440x900 monitor. The second card would basically be pointless.
  5. Id say don't do it, a 9800GX2 performs like a GTX460, which is just a 9800GTX SLI down-clocked to 9800GT speeds, the performance upgrade at stock speed would just be ~10%.

    Besides, at your resolution, you wont benefit from that extra 512MB of V-Ram.

    Unless you really want DX11, OC the 8800GTs for now and wait for the GTX475/HD6000..

    It's a 1gb GTX 460 for $120. There's no reason not to do it. The actual cost will be minimal if he were to Ebay the 8800GTs.

    A 8800GT sells for $60-80 each, so the lowest cost for the GTX460 would be still $60.
    $60 for a 10% speed boost, DX11 and lower power isn't worth it IMO.

    Go for it.
  8. Did you miss the first sentence of his post(or mine)?
    The GTX 460 is $120. He has 2 8800GTs. Using your numbers at worst the card will cost him nothing and possibly he will make up to $40.

    I'm more confused by that, a 9800GX2 is a down clocked 9800GTX?

    I meant in SLI..

    ^^ DID NOT SEE THAT.
    :heink: Nevermind, go nuts with the GTX460, make sure it works.
  11. Thanks for the advice! I'll give it a shot and sell off the 8800s to bring the cost down some.
