Ati 4870 - PCI2.0x2 Tags: Radeon World Of Warcraft Graphics Last response: April 21, 2010 7:33 PM in Graphics & Displays Share stevos March 25, 2010 12:58:12 PM Hi, I have been struggling with performance with world of warcraft and trying to find out what is the weakest link. When checking the catalyst drivers (latest version) i notice that in the system information it is reporting max bandwidth of PCI2.0x2 rather than x16 When i run CPU-Z it shows the slot is a full x16 version. Any ideas what i might have done that has caused this? Motherboard Asus p45 P5q CPU - Q9550 overclocked to 3.4ghz Cheers Steve.

Will run 3dmark on it tonight and see how it compares, hopefully it will be inline with what other equal systems produce.

Maziar a b Ý World of Warcraft March 26, 2010 2:09:58 PM I couldn't fix it i bought a new GPU(Because the warranty time was over) stevos March 26, 2010 2:58:33 PM Not the answer i was looking for lol. I have been tempted to buy a 5870, but realistically i only play world of warcraft on my pc, and i suspect it wouldn't come close to pushing a 4870 let alone a 5870. Maziar a b Ý World of Warcraft March 26, 2010 4:06:00 PM Yes a 4870 or even older cards can handle wow fine,is your card still under warranty ? stevos March 29, 2010 8:49:27 AM Not sure. Still not had a chance to run a benchmark, really got to do it soon, just incase there is some warranty remaining. stevos April 21, 2010 7:33:30 PM Is there any chance that the PSU isn't up to the job to support x16? If the PSU is bearly up to the job, what would you normally expect to happen? Can't find your answer ? Ask !
