If you cannot change anything but the CPU I caution you to nothing at all. Putting in the q9650 without a adequate PSU and cooling will doom you PC to live a short life at best and not work at all possibly breaking your PC altogether at worst. You may get by with the stock cooling you have now depending on your ambient temps but running a 305W PSU when you should be running 375W is begging for a problem. I am not saying it will not work but I am saying I would not do it if it were my PC or a family members. All we can do on Tom's is try to give you the best advice we can, whether you take it or not ultimately the choice is yours.

Well there a couple issues. First you need a larger PSU. Dell requires 375 for higher end quad cores which brings me to your larger problem. Officially Dell does not support the q9650 with that board but I see mixed reports about it working.Also you would need a new heatsink as the one included with your CPU is not adequate for the q9650. try reading these.

yes his computer is an OptiPlex 755 from dell as he describes it.

@Arslan_24
your Motherboard is known as the Dell Optiplex 755 Motherboard GM819
upgrading to the Q9xxx can be tricky and with little information, not to mention contradictory.
I have found this tidbit on : http://en.community.dell.com/support-forums/desktop/f/3514/t/19537919

Officially, (according to the Dell Technical Guide Book for the Optiplex GX 755)  the CPU is Intel Core 2 Quad Q6700 Processor (2.66GHz, 8MB L2 cache, 1066MHz FSB, VT) 8GB of DDR2-800 (PC6400) non-ECC memory
I also found this list of CPUs and RAM that was posted by Kisianik on Tom's Hardware forum. It shows some faster CPUs and RAM speed (in Mini Tower Only). This is the list of processors which will work in your Optiplex

N652J 3.00GHz Yorkfield Quad Core Q9650, 12MB
F886J 2.83GHz Yorkfield Quad Core Q9550 12MB, 1333FSB, E0
N650J 2.66GHz Yorkfield Quad Core Q9400, 6MB, 1333FSB, R0

Those 3 above were validated by Dell engineers, and below the rest of general processors from another list.
Click to expand...

I looked into the chipset of the 0gm819 motherboard and its Intel Q35 Express and that chipset supports the previous statement on this page
http://www.cpu-upgrade.com/mb-Intel_(chipsets)/Q35_Express.html showing the Q9550 and Q9650 should be compatible CPUs for the chipset.

I cannot find PROOF someone actually done this. so your a little on your own, make sure you have a good power supply on that unit. (look at the label it would need to be at least 300w and likely a motherboard bios to latest version will also be needed just to make sure.

to put it short....you cant upgrade an old dell without sinking in more $ than its worth. when all is said and done we have built computers that cost 500$ and when YOU get done rebuilding your dell it will have cost you 500$ in the long run.

you bought a potato with no upgradeability.

the Q9650 costs 65-75$ on eBay. new cpu heatsink and fan are at worst 45$, 60$ if you get a watercooler like a LS120S. or H55i from corsair
far cry from your "500$" scream of death.

not everyone needs bleeding edge nor can afford bleeding edge technology. 100-130$ upgrade sometimes is what all people need on their machine to use them longer...

when your battery or water pump is getting old on your car? do you change car ?

if i bought A PREBUILT and have to come to a second party website to find out if i need a upgrade it means i have done research from DELL to know that im HOOPED. OP should have known that in the first place and now is asking questions for alternatives. psu and gpu...when doesnt have 200+ fps in COD he will wonder why. * getting tired of "i have a potato i wanna game on" posts*
