Hi

I have a [ga-g41mt-s2pt] motherboard and a Q6600 cpu

Wanted to know which of these options would be better in order to improve performance safely

Overclocking my Q6600 to 2.8-3.0ghz which I read is pretty safe and relative easy (up to 3.0)

Buying a Xeon E5450 which runs at 3.0ghz out of the box (currently 22$)

Was also considering buying a low tdp L5430 (currently 15$) which runs at 2.66ghz 50w tdp (compared to the Q6600 2.4ghz 105w tdp) so a slight more performance with half the power consumption.

I also have an Alpine 64 pro cpu cooler if it makes any difference.

I've found the Q9505S for $20 and that's why it was included. But yes the Q9650, and Q9505S ARE pricey. The X5470 can be found cheap sometimes and are as good as it gets anyway. X5460 3.16GHz can save a few bucks also.
Here's the page for the Xeon MOD.

I bought my Optiplex 380 for $20, Q9505S $20, SSD $40, 2x4GB DDR3 1333 already had some. The Q9505S you don't need a cooler upgrade. I tweak mine a little with SetFSB and it equals Q9550S and Q9650 scores anyway. I own an X5470 but haven't done the mod yet.

The Q6600 pinmod to 3.0GHz is a classic but it only equals a Q8300 in performance and burns Watts doing it.
The simplest solutions are the Q9550S, and Q9505S which are 65W LGA775 CPUs. No mod required. Q9650 is 3.0GHz also.
BUT if you want to get serious at userbenchmark.com

I'm seeing Core 2 extremes running. This means it can run 130W CPUs.
QX9650 is king of the hill, But X5470 3.33GHz would be a good mod also.
The 3 best options would be QX9650 and see how far you get with an overclock, X5470 best non OC option, or Q9550S 2.83GHz low power, and if you can get control of Voltage and FSB on that MB then the most headroom for an overclock.

Thanks for the replies but perhaps I should have been more specific - I was considering these options due to a very low budget, I can't afford to buy a decent SSD and the Q9550s starts at 50$ going up and the QX9*** are way over budget. I need a value option so I can spend some cash on more ram. Currently 4gb ddr3 1333, so I want to upgrade the ram to 8gb which is the mobo max supported.

BTW- yes this mobo support a Xeon

The base Q9650 isn't too much, X5460 also. both of these are way beyond the Q6600 overclock.
There are 2 X5460 SLANP and SLBBA which is the newer E0 stepping. For the same price i would get the newer one.
