High end system with low FPS issues

Hi,

I just built this new system and it works fine most of the time. But, when I am playing Halo (1) and World of Warcraft, I get frame rate issues at times. I checked on heat and both video cards are staying under 50 degrees C. I have been playing CoD:World at war, which came with the cards, with no problems but some tearing that likely would be fixed by vsync. I have tried a lot of different settings in Halo and get the same results unless I turn all the graphic settings down to where I might as well be using a 10 year old graphics card.

Halo seems to drop down around 10 FPS for a few seconds then go back up(I know of know way for it to tell me FPS). WoW dropped down to 0.8 FPS for the last half of a long fight. This means it was handling all the same graphics before. When the fight was over it came back up to about 65 FPS and was fine thereafter.

System specs are:

Asus P6T MB
6 gig of Kingston DDR3 1333
2 EVGA GTX 285s
HT Omega Claro sound card
Vista Ultimate 64bit
WD 300gb Velociraptor

I have a case with 2 10 inch fans built in blowing in for cooling. As I said the video cards are not getting very hot. Please help, I have no clue what it could be other than a Vista issue. I ran the same 2 games on a lesser machine running XP with none of these issue.

we can always start w/ the obvious
do u have the latest drivers? Check the nVidia site and get the latest beta drivers.
Do u have allot of background tasks running?
things like virus scanners, torrents can kill fps. Also, if you have windows media center active, the downloader for the tv guide can sap up cpu power. I'd look to see if any of these things are hurting your frame rates

Yes I have the latest drivers. I haven't tried beta drivers yet. I wouldn't think with games this old they would make a difference, but I will give it a shot. I tend to keep background programs to a minimum. This is a new machine so there is not much on it. No anti virus installed but no risky behavior and windows stays updated.

There was a torrent that installed itself yesterday and I disabled it this morning. The problem still exists in Halo. Looking at CPU graph, I wonder if it's topping out the single core it would be using. It does seem to be only when the action is hot and heavy.

your two GPUs alone will take allot of power

1200 watt. I would hope is enough.

1200 watts should be more then enough, as long as it supplies enough voltage through each rail

It's set up with one set of wires coming out for a vid card, 2 for mobo, and 3 more plugs for hook ups to the vid cards. 3 more for peripherals as well. I only have 2 drives in there. Plus the 2 25cm fans (they really aren't quite 10 inches). Case has room for 2 more fans, but things seem to be staying cool enough atm. There are 2 power hook ups on the back of each video card and I have them both powered.

Thinking about that processor, that should be more than enough for Halo, I played it on a 1.8ghz athlon when I first got it with no problems.

Beta drivers fixed the issue. This made no sense to me till I went to the EVGA site. The latest drivers there(which have the same version number as the ones on the nvidia site) only support up to the GTX275. I am guessing the drivers I was using didn't support the cards. Thanks for the help.
