maybe.....What procecssor?? q6600 does not register in my brain. is it Intel? AMD? (SUcKS!!!) oddball? i tried to upgrade my Pentium 2.0 Ghz processor in my 2 year old computer, but you need a special power system for all i3, i5, and i7 Intels. (wasted 200$ on a i5 that didn't fit! now it's just collecting dust on a shelf.) but otherwise, yes. the CPU does not affect the HDD where the OS is. The OS may have problems with the change in CPU clock, as timed operations in the windows Kernel will not measure the clock speed correctly causing it to crash some drivers and/or the whole system. it's also possible that the CPU will screw up on first boot and not do the correct HDD detect procedures. make sure to run and check BIOS. (for common BIOS startup keys, DELETE and F1 are most popular.) You shouldn't have a problem.

Have you seen the price of the QX6850? It's pushing $1000 these days. Do you realize that it's an enthusiast's CPU, much like the AMD Black Editions? It has a fully unlocked multiplier for overclockers to go wild with. All of that goodness goes out the window in a Dell system though.

Your system doesn't appear to support 1333MHz FSB & probably doesn't support 130W processors either. And I'm fairly sure the factory power supply would never support such a CPU, so you'd be looking at a major investment for a minor speed increase. If you had a decent motherboard, you could easily overclock the Q6600 to at least the same speed as the QX6850 (3.0GHz), but alas, you have a Dell.

In other words, you could build another system custom that would get you close to, if not more performance for the same or less money. You could purchase a 2500K, MB, PS, RAM, DVD, HD, case, and Graphics card for the same or less and overclock it nicely for a really fine machine. You could then sell your old system to recoup some of the money, or do it first and go with a 2600K and a better graphics card even.

You have to be a little bit crazy to keep you from going insane.
