FPS spikes on new M17x-R2

I just recently received my laptop and all in all I am very pleased with this thing. It performs like a dream come true but I have noticed some problems that I'm concerned about. I took the time to use the search function before posting this but maybe I didn't look hard enough because I couldn't find anything real helpful. My concerns are this: last night I had my laptop running all night and awoke this morning to play L4D2 as I joined a game the fps was extremely choppy and made it impossible to play so I quit the game and did a reboot which fixed my problem and was able to play at a constant 60fps. This was the second time I had to reboot due to choppy fps and it also happened in WoW. I am running the stock dell drivers that came with this laptop. All in all this laptop performs quite perfectly to my liking despite the choppy fps that causes me to have to reboot my system. I'm probably assuming that crossfire is disabling itself sometimes which is why I'm experiening this lag but any input from you guys out there would be appreciated as I would like to pinpoint why my laptop is doing this.

 

/Bump with hopes of getting someone who can help.

 

Hi theres,

I'm not too sure about your problem as I own the R1 however you could perhaps try the newest 10.8 driver which Dell recently released a couple of days ago. Also Dell also released a new BIOS revision A07.
Give those 2 a go maybe and see how it goes. Cheers.

If the games are like Wow where your online. Check the game timeline. Alot of times if you are on when the servers that has alot of people at one time Everyone get lag. Then try at times when it has less people.
