Much more so than overclocking the CPU regardless of whether the second card will be operating at 4x or 16x speeds...
Actually, it can give u a HELLA performance boost in gaming. Specially with crossfire. If ure Core 2 is at a 1.8Ghz stock, it will majorly bottleneck ure GPUs. As a result, u won't get what u expected with CF. And from 1.8Ghz to 3Ghz, u can expect as much as 10FPS increase in some games...
here is a chart comparing CPU performance in UT 2k4

Yeah, I guess I forgot the added factor of crossfire--good point! I always forget how much the CPU can factor into a CF (or SLI) setup for performance considerations.

edit But to comment on the THG of CPU charts--I lost all faith in their charts ever since their VGA charts came out mid last year (with major issues--like in BF2142, they showed only 32-odd fps at 12x10 res and full detail for an x1950pro--I always get between 55 and 75fps minimum with my x1950pro)--and I suspect their CPU charts are incorrect. Because stock vs. stock, I had an X2 4400+ system before my current sig rig, and my current sig rig is in every way faster--twice as fast at audio encoding, but TH says that the 4400+ is faster than a E2160 for audio encoding at stock speeds (they don't have a 2180 on the list, otherwise I'd cite that)--which is not the case. So I wouldn't put too much weight in the THG charts--they always have something funny going on with them...
