    Yeah so here's the deal. I'm not unhappy at all with my non-reference version of the Sapphire 4870, but like most of us, I of course want MORE!!

    Now the price on a 2nd one is not an issue. It more about my MoBo and my gaming resolution and is it really worth bothering

    I run an IP-35PRO which has 2 PCI-E slots but as far as I know when running 2 cards its gonna drop the slot speeds.
    I run a Samsung 204B 20" monitor that runs at 1600x1200(what can I say I like 4:3)

    So anyone got any good advice? I really miss my Opt 170/ X1900 CF rig that was fully watercooled, it really was a screamer.

    P35 cant do crossfire well at all, it will be complete fail.

    P35 is PCI-E 1.1 so your at half banwidth already, but the second card will run a x4, way too slow for a 4870.

    You need a P45/X38/X48 to run 4870 Crossfire properly.

    You will be throwing money away trying to do 16x/4x PCI-E 1.1 4870 Xfire.
    INSTG8R says thanks.

    Yeah that's kinda what I was thinking too. I cant be bothered upgrading the MoBo as my CPU would need an upgrade too as it is getting long in the tooth as well.
    Ah well I will probably moving back to Canada sooner than later and will prolly have to sell the whole rig anyway.

    while ATI in crossfire scales really good, and the drivers are mature enough to cause little trouble, im still not a fan of it cause in my opinion if a single card cant run a game, its not worth getting a second card for.

    if you really wanna go for a upgrade, and i only advise you this cause you have a 512mb card, go for a 4890 1gb.

    Above 1280*1024 1GB starts to make a good diference, especially for lowest fps, and the additional mhz on the core give another good speed up, which should give you the edge you are looking for, without spending alot of money, cause your 4870 has a high resale value :)

    From personal experience after building my bro his rig with a 4870 1gb, he plays any game at max settings perfectly at 1920*1200, so 4890 will be all ya need, if you got any questions on details hit me up.
