    I put my desktop in storage for a year because where I was living, I had no space for one, and was using my E6400 laptop and doing everything I needed except gaming which I don't game much anymore anyway.. Now I got a desk back and was going to plug in my now dated powerhouse desktop ( AMD Athlon X3 445 Rana, 8gb of Corsair Vengence, MSI 7790 video card and a Biostar A770E3 mobo ), and I decided I just wasn't going to use that much processor anymore. It has an XFX 650w power supply and with all the fans, sounds like a vacuum cleaner.. gonna sell it

    So I pulled an Optiplex 755 desktop from my old sale stuff. I bought 4 or 5 and this is one I never sold. Pulled my desktops hard drives and swapped them in, stuck another 2gb of spare ram in it. Re loaded win 7 ( modded bios ) and been running it for about a week.. I'm dealing with it. it's 'as fast' as the laptop. But I wouldn't mind a Q9650.. Then got thinking about the LGA775 Xeons. wouldn't a 3360 work with another bios mod? they are roughly half the cost


    and what about video card? I only want to play games I already have. GTA IV, Singularity, Bioshock, Garys Mod and Dirt 3. If I can play them with xbox 360 like quality, I'm ok with it

    So, I should be able to run a X3360 processor ( LGA775, no LGA771 conversion ) with the latest bios? currently running an old modded bios that is A19 with Dell SLIC 2.1

    Incorrect, do not buy the Xeon.

    You cannot use any Xeon processor as the Xeon is not officially supported. Even though it will probably work, there lays a big risk of incompatibilities; especially in the BIOS settings of your machine.

    The Optiplex 755 is G31/G33 chipset, Xeon compatible chipsets: Intel 3200, 3210.

    Your computer is not a server nor Dell a precision workstation. Plus apparently you can only support quad core w/ 1066MHz FSB compatibility, x3360 is 1333MHz.

    Q6700 is your best bet and you can pick it up for $30 (£25)

    He said he has a Dell Optiplex 755 not a 775.

    Looks like I'll be ordering a Q6700 off Ebay.. According to the Dell forums, a Q9650 has been verified by Dell to work, but $80-100 processor is out of the budget for this old computer. $30-35 is more my budget..

    These machines cost me $60 each shipped 3 years ago. So figuring my costs at this point, I have $4 into a 2.5-3.5" drive adapter and $3 into another YJ221 drive caddy. everything else was out of my spare stock.. If I can keep my costs under $125 for the improvements, It'll be pretty sweet.. It is a downgrade from what I had, but the silence of the tower is worth it

    Another useful thing to add is a PCI-e USB 3.0 adapter card. Adding USB 3.0 to these machines really speeds up transfers. I added a USB 3.0 card and a USB 3.0 hub to my Optiplex and it really increases backup speeds to an external hard drive or USB flash drive. You can get a USB 3.0 PCI-e card for $20 or $25.

    I was planning on a PCI-E SATA III/ USB 3.0 card. there a little more money but, I have a 250gb 2.5" drive salvaged from a dead laptop that I can put in my 2.5" drive adapter since it holds 2 2.5" drives. I have it mounted where the floppy would go, but I'm maxed out on SATA ports without it connected
