i just built a friend a new system from spare parts. it has a 2GB, 2 1GB and 1 512 MB stick of DDR2 667 ram in it. an asus budget board i had lying around, a phenom X4 9650, and a 5870 radeon. playing diablo it seems to be starving for data. CPU sits at 30%, GPU at 60%, HD sits around 15MB/s read/write. the HD is a WD blue 500GB. what do we thing, how much is the CPU bottle necking the GPU? this was a build for 300.00 wich is all he had so i did the best with what i could find lying around.

windows 7 ultimate clean install.

The CPU is not a problem for Diablo 3. The RAM bandwidth might not be high enough, but otherwise, I don't know what could be wrong, unless you don't have all of the latest drivers for that hardware.

everything is current. i notice that with the avast anti virus off it runs smoother but... i cant figure out why that would impact a quad core with a 5870? im pushing him to buy a SSD when he gets some spare cash again but idk... i havnt used a platter HD on the OS for 3 years but i dont recall them being that slow?!?

if it has two 1 one g sticks and one 512 stick and one 2 gig sticks...i would put the two one gig sticks on the same color bank and then put the 2g dimm by itself. most mb vendors want you to use match dimms. and in the same bank.. having mismatxh ram sizes is not smart.

On second thought, you might also want to OC that CPU, if you can. I just checked it's clock frequency and it's a little slow for the 5870. Remember, 30% utilization might mean that one core is fully utilized while the others are practically idling.

it displays 30% across the board, no one core is being maxed. to much to do so i havnt had any time to look into it yet but ill post back what i find

Would you provide a screen shot of that in your task manager? I'd like to have a look, if that's alright. Also, make sure that you don't have anything running in the background that shouldn't be running.

i ended up disabling super fetch and running 750MB of ram as HD cache. that seems to have solved the issue and D3 is no longer lagging under max settings
