How do you know your cpu is your bottleneck? I read here and there that most games are not cpu hungry?
From what i've read;
For getting the max out of an 4870x2, you need at least an cpu with 3Ghz.
What i understand from it, is that when the 4870x2 is running at max speed, the cpu with less than 3GHz cannot keep up with the speed for giving data towards the gpu.
About most games not cpu hungry, im not really sure.
Most normal games, like FPS, they run fine on a normal cpu.
But i think about "simulations" are a bit more demanding.
The computer has more things to calculate.
A very good example is FSX.
With simulators, most people have also some other programs running on the background (Motec, Teamspeak ect)
But the computer hardware is getting better, and faster.
Therefore software developers are (trying) to make more heavier games,
just because we "gamers" are "demanding" that from them.
So we can have full joy of our "uber" systems.
Future will tell.
How much fps do you get in GTR Evolution? And in what resolution is that?
I just did a quick run at monza.
Resolution at 1920x1440x32
All setting on max, except Shadows on High, and Shadow Quality on High.
19 Opponents
At Grid (start) 46FPS
Race - A very few times hit the 47 low, and 76 high.
Most of the time it was between the 52 and the 67.
Your FPS isn't that great (20)
You should try to get it at 30+.
The normal human eye, cannot see the frames, when the FPS is over the 30.
Do you have alot of programs running on the background?
Regular defrag? (Manually or auto?)
Is your OS clean? (no unwanted programs. You can check this with HitmanPro for example.)

In the days, when i was in the flightsim community, alot of people made use of FSAutostart.
It was a small program, just for gain some more ram.
(You could turn things off in windows, wich you didn't need)
Im not sure, if you gain something with it in GTR-Evoluion.
It seems there is a new version of FSautostart;

There's also a possibility to tweak your Windows a bit,
by turning some services to off.
I did it always, in the days with XP.
Here's a good info site about it.
