When I had my C2D running at 3.4ghz, I had about the same performance as you. That game rapes CPU's in the asshole. You're best bet would be to just buy a Core2Quad, since you should be able to use the same mobo. That would fix youro BC2 frames.
The song that first turned me onto Tim. Now I own both of his DVD's and would die to go see one of his shows if he comes to the US.

/spends nothing on my water and will not have any health problems from it either.
I'll probably end up dying from the million of other things way worse for me than fluoride in my tap.
I figure this wouldn't get enough views in the Video Dump, and I am really rooting for Tim to have a US tour...so enjoy! For those who have already seen most of his stuff, you'll probably be a little bored, but alas, have some Inflatable You...
I currently use the 25" Hans-G, and besides one that died in the first few hours, it's working out wonderfully. I also have a 22" Hans-G that was my primary for a year and a half, now my secondary. Both are great monitors, look great, and I use them both for gaming. Also, great price.
*EDIT*...
You're not getting worse, you just went backwards because you didn't play much, if at all, for the longest time. You're starting to catch back up. You're doin' good!
