I have a Gateway P-6705u, with a X9100, eight gigs of DDR3, a one gig 9800M GTS and two hard drives. Recently I have been having horrible overheating issues. I just put new thermal paste on the CPU last week but I still can only play Arkham City for about 20 minutes, on all the lowest settings, then it shuts down from the heat. I do have it propped up, but I do not have any extra fans underneath, I have found they do not help. I am considering getting a T9900, but am looking for other options. Also, would a T9900 even help that much?
