May I ask what ram u currently have rigged now? if anything, the heat shouldn't raise more than a degree or two. I also agree with Shadow on the heatshield. I have seen a differebce however with loading screens for bf2 with 2 gb in comparision to 1 gb.
I'm a huge fan of corsair ram, if you are in any debate on what ram to buy. Myself, I would personally go with corsair xms ram. I have it in my rig and it's amazing. I truely think its the best ram out there right now, not even patriot ram is better.
My thoughts of course, welcome to opinion and debate
