Hello everyone

I'd like to ask some of you guys Q9650, QX9650 users.

I've been lately thinking about changing my Q9450 CPU for Q9650. Even QX9650 as there were few in my area secondhand same priced as new Q9650s. That might be a little upgrade as I don't want to switch to I7, DDR3 because of lack of funds for it.

I just wonder how much performance in games would I gain while using CPU let's say 4.2- 4.3GHz (well, because I use quite efficient cooling, might be 4.5 GHz for 24/7) as compared with 3.8GHz? That's the CPU clock I've been running lately. What do you guys think? I consider here only CPU clocks speed and how it affects the games performance.
