    I have an HD4850 and I want to upgrade but I have a small budget, I have two offers then : an Asus HD4870 1GB or Asus GTX260 (192sp) with 4870 40 Euro dearer
    I'm a fan of overclocking, which is the best by you and which overclocks easily, I'd like to have performance close to the HD4890 or GTX275/280.
    I play in 1600x900
    Thank you

    hi there it's hard to tell IMO the 4870 is the best option BUT you are NOT going to get anywhere near to 1ghz core clock any 4890 does, still 850 Mhz is possible so go for the 4870

    Hmmm...that is a rough choice...

    At stock, the HD4870 ever so slightly outperforms the GTX260(192). The GTX260 being a 192 SP version means it is the older 65nm core, which doesn't overclock as well. However, it should still overclock way better than the HD4870. With the GTX260 you are looking at about a 20-25% overclock on both the core and memory, even more if you use eVGA's voltage tuner to raise the core voltage a notch or two(All 192 SP GTX260's had software voltage control). With the HD4870 you are looking at about a 10% overclock on the core and memory. But the overclockability of the HD4870 really depends on if the model you are looking at supports software voltage control, not all did. If it does, then you can get better overclocks, maybe in the 15-20% range.

    In the end, I think I would go with the GTX260. You don't have to risk getting one that doesn't have software voltage control, like you do with the HD4870. And overclocked it should outperform the overclocked HD4870 without voltage control, and at least match an HD4870 with voltage control.

    I think there is no sense to change from 4850 to 4870 or even to 4890. You cannot FEEL that difference in performance. I think you should wait for 5850 prices drop. I believe it will drop when Fermi comes out (I think nVidia will release Fermi key-chains first :) ).
    You can always pencil-mod and overclock your 4850 from 625MHz to more than 800MHz and it will perform similar to 4870! I've had mine HD4850 clocked at 850/2300 without any problem.

    If you're dead set on upgrading than go for it but I say wait till you get more money than go 5XXX series.

    Welcome to TPU BTW....:toast:

    ya i feel that anything other than a 5800 series ( even a rumored 5830) is the only worthwhile upgrade from a 4850. Anything else in the 4000 series is more of a side grade (unless its an X2 at a steal!!)

    Sidegrade...The newest word for the Oxford dictionary.

    brilliant word!

    Can you borrow from someone GTX260? I did the same when HD4890 came out. I was dying to change my HD4850 for that monster. I've borrowed HD4890 from my friend (he works in computer shop) and tested it. HD4890 was 20% faster and 100% more expensive. There was no point for that change.

    When I changed my HD3870 to HD4850 it was 80% faster and only 50% more expensive. Think about it!

    For 1600x900, IMO, would wait a little longer for prices to drop some. Although with that being said your getting either of those cards at amazing prices. I'd opt for the GTX260, it scales a little better with an overclock.

    I wouldn't call a 40% performance boost(stock vs. stock) a sidegrade...

    Of course, if his HD4850 is a 512MB model, it actually be slightly more than 40%, closer to 45%.

    first of all and before thinking of changing my card i voltmoded my card to reach the max of it, but the card hit some annoying temps so i have to buy an aftermarket cooler that cost 30-40€.
    so i can sell my card, add that 30€ and buy directly the gtx260 from a friend.
    the asus 4870 is new and i have to add 70€ instead of 30€ (i said in the beggining that the 4870 is 40€ rearer)
    so i think the GTX260 is a better choice, i can rise the voltage with the evga tool and overclock it to some good clocks ( i think :) )
    i have see this review of the some card but in "top" version
    http://www.generation-gpu.fr/articles-Asus-GTX260-.....-Le-top-du-top-,ar317-8.htm
    it can hit some good clocks and performance
    i think the top version of all asus cards is simply a soft modification of the original card, they rise a little the clocks, change the fan setting by increasing it's speed (am running now with a bios from the top version) so it can hit 100% from 70°c and they rise the voltage adding 0.05v in charge (this from my experience with the 4850)
    what do you think ?
