Nooooo, please not tell wrong things and read phat's technical thread. It is NOT the RAM memory!!!!! It is in first priority the VRAM memory (the memory on your videocard)!!!!!
If you run out of this memory, it swaps to normal RAM at second stage. But than it is already too late, because a normal RAM is generally slower and is far away from the videocard with a slow BUS. All RAM memory afterwards is simply to slow to do athis amount of work fast enough. It could help to gain some performance with faster RAM, but the main problem: "running out of VRAM" still remains unsolved. Just concerning the memory bottleneck!

I am talking to/about someone who I presume has already got a nice video card. If they have that, then the next possible bottlenecks are CPU and RAM. A Core2 Quad at 3.0 GHz (or faster if they overclock it) might well be fast enough. Old slow RAM is old and slow. Certainly more RAM on the video card is good, and there again slow RAM may be a problem, most high end video cards since years ago have used DDR5, but some lower end graphics cards use DDR3. DDR3 is as fast as you can fit in a PC, but for graphics cards DDR5 is available, and apparently it's something like twice as fast.

So perhaps a little misunderstanding, but giving the initial poster advice about RAM as bottleneck is misleading, too!
 Gain fps with videocard and its vram. Secind step, when still having problems: upgrade cpu and ram, but cpu should in this case have less influence, although another, faster clocked cpu with ddr3 ram is apprecuated , too. I do not exactly know, if the quad and its ddr2 in his case could also be a bottleneck afterwards.... As I have an old i7, I am currently not running in any priblems and the 2 fps more with a new generation is too expensive for me, because the watercooling also costs some money. First of all I will switch to eyefinity with 3 monitors. Later, the cpu will be substituted.

He or she is talking about buying a Core2 Quad as an upgrade. That means he or she has a motherboard with a LGA 775 socket on it. A lot of those motherboards, not all but some (particularly old ones, and if he or she has had it for years already running e.g. a Core2 Duo it will be old), take only DDR2, and the fastest DDR2 you can get is 800MHz. If he or she already has a very fast new graphics card, and a Core2 Quad, DDR2 on the motherboard will be a potentially serious bottleneck. Spending money on a computer is a balancing act, if you buy two fast items and leave a third slow, it will be the slow one that is the bottleneck. Better to spend a little less on the first two, and upgrade the third as well. Knowing what is relatively slow is difficult, but in this case, in my opinion, DDR2 is a very serious potential brake on the system.

You are totally right. Just directly talk about memory and that it is the bottleneck at first was a little misleading, because not knowing all specs. But it is okay as you told him now. There was nothing wrong. So, everything is clear now.
One last thing: I do not know prices, but I can imagine, that you get an i7 or i5 for nearly the same money. Just a mainboard and new memory should be affordable...

My specs are in my signature, runs the game decently all though with quite a bit of stutter and the occasional 1-2 second freeze (Due to the slow DDR2 ram).
CPU usage analysis confirms that the CPU and RAM are the flaws in the system, the 6870 runs surprisingly well! I run locked at 40fps by Bandicam, fps usually varies from 25-40 depending on where I fly. Some issues with textures.
