Where's king? He got a q6600 in his Optiplex and he did the BSEL mod on it. He's got a OEM Dell Pc overclocked to 3.2ghz stable lol. OP you can wait for him he knows everything about upgrading Dells but to my knowledge q6600 is the highest you can go. Those you listed are extreme versions and cost more than the new SB platforms you might as well do a mobo, ram and cpu upgrade then


Thanks Dadiggle
But actually it is an E4300 1.8 800mhz pin modded to 2.4 1066mhz
Just bought a E4500 and will try to get 2.93ghz with pin mod :) 

With that said
The 745 only offficially supports E2xxx,E4xxx and some E6600
they have to be 65watt, 65nm and no higher than 1066 FSB

I have read threads across the web stating that a Optiplex can support
q6600 BUT considering they are about 150 to 200 USD right it
really doesnt make sense to buy one for an Ole Dell Opty :) 
Dadiggle is right
at that price might as well do new build
You could almost do a X 3 Rana mobo/cpu/ram/psu for that amount

I did get my E4500 for $50 shipping included so
I figured why not
I can end up with an Optiplex 745 with a 3.0ghz (2.93) Core2Duo
I love making OEM pieces of crap do things they were never meant to do LMAO

Hopefully I dont have the magic smoke leave my cpu....
they dont work right without the magic smoke in them LOL

techically the fastest two without
mods are
E4700 and E6600
and now it is proven
it can use a Q6600
but that is 2.4ghz with 4 cores

the E4700 is quicker (2.66?) but only two cores
but half the price of q6600

I figured pin modding the E4500 to 3.0ghz for $50 was
best performance to price deal

system specs are

Optiplex 745
hopefully 3.0 E4500 1066mhz fsb 2mb l2
4gb Gskill DDR-2 800 (BTW the 745 will only support 8gb with 533/667 ram not 800)
250gb seagate barracuda 7200rpm Sata 3.0gbps
Sapphire 1gb HD4650 OCd (planning on getting a HD5670 soon)
Asus Xonar DG
280w Dell PSU
Liteon 16x Sata DVD-RW
Total current cost - $165

I dont know if the OP will post back
but if you need help let me know

Thank you David
I have been looking for that screenshot
I hope one day the Q6600 will be cheap enough I ebay
and I too will have a Quad Core Opty 745

The Dell Dude would faint :) 

Dell 745 SFF W/q6700 geekbench http://browser.primatelabs.com/geekbench2/1111369 highest score for a dell 745 suppose a
QX6800 would go higher..The Dell 745 supports Pentium D,s to 130 watts so it should handle a QX6800 if someone has one handy
also supports graphic cards to 75 watts such as new SAPPHIRE 100357LP Radeon HD 7750 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Low Profile Video Card uses 60w MGP would make a great game playing combo.
