here are your specs
Intel Core 2 Duo E6700 Kentsfield or Quad Q6700 Kentsfield 2.66GHz would drop right in and work. Just be warned that there is a Wolfdale E6700 (3.2Ghz) that will not work.

(SOLVED IN THIS THREAD) GPU READ THE SOLUTION AND LAST POST!!!!!!

I was going to tell you tell you. the 750ti single slot design should work since is low wattage and only need 300w PSU. your system has a 305w psu in it already... you should get and better psu but the one you have will work

you have a socket 775 here is a good cpu for your machine.....providing you don't already have a q6600 in it already

Mini tower is the biggest one right? I have that exact same one. The issue I found was that due to some big capacitors and the strange facing PCIE slots which make your GPU go fan up, the heat sink cannot fit. so either a really low profile card is needed, or do what I did and get a PCIE riser. as for CPUs I upgraded to a Q6600 I found for free, and it has made quite a difference. you can get them quite cheap and they can run GTAV if you are into that kind of kill everyone stuff. the 3.0 GHz chip is nice but it is overpriced often.

MatthewMcLaughlin · Aug 5, 2015

i believe i may have told you the wrong type of optiplex i have, thank you for showing me, i have the desktop model,
can you suggest suitable cpu gpu and psu that is suitable for my pc? thanks

Robert Cook · Aug 5, 2015

so the one that lies flat on the desk, like on its side?

MatthewMcLaughlin · Aug 5, 2015

yes you are correct

just after ordering a q6600 cpu

corndog1836 · Aug 5, 2015

MatthewMcLaughlin :

the cpu selection sent to you earlier is the same q6600 will be fine.

that's about the highest he can go .....double check me....

MatthewMcLaughlin · Aug 5, 2015

thanks for the suggestions, are you 100% sure these parts will fit because as you may know the optiplex is very short of space

corndog1836 · Aug 5, 2015

the 750ti low profile length is the same as the specific video card for your system

the 750ti low profile width is 1.2cm bigger (VERY SMALL) it should work!!!!

Kisianik · Aug 6, 2015

I don't want to spoil your party but original question was

best graphics card to fit dell optiplex 745 desktop?

So look at the pictures below, which Optiplex you actually have?

If it is Mini Tower, then Best Solution is more or less correct, if it is Desktop there could be some issues like no PSU upgrades, only low profile video cards.
By the way, I seen something here about CPU upgrade to Q6600, I just wondering, which CPU cooler OP has aluminum or copper (requirement for QUAD CPU).

MatthewMcLaughlin · Aug 6, 2015

Why do you mean by the cooler? The big huge metal thing that sits on top of the cpu?

MatthewMcLaughlin · Aug 6, 2015

Thanks corndog for all your help

Kisianik · Aug 6, 2015

corndog1836 :

My turn now.

So it is Desktop (DT) form factor, very bad, lets go through your answers.

2. Let go to this thread and investigate, shall we?

I own the optiplex 745 desktop version (the version before the minitower)

That poor guy stated that he doesn't have Mini Tower, but the next to it (look at my picture), which is DT form factor.

And now look for the BEST SOLUTION

I have installed standard ATX PSUs into similar Dells, including an Optiplex 745 MT

This is not correct answer, because OP has DT not MT version. Best Solution is selected by ErVivek, which is, as I been told in the past, is some kind of automated system designed to find solutions, sometimes it works, sometimes it doesn't.

So, let me show you my point.
Lets look at your choice PSU
Dimensions 5.9" x 5.5" x 3.4"

Now let see the outside dimensions of Optiplex 745 DT version I will place measurements in correspondence to Seasonic dimensions
13.9" x 4.5" x 15.7" source https://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf

Now lets actually open side panel and look inside, shall we?

So, Power Supply upgrade suggestion is incorrect, agreed? However, DT version has 280 watt PSU, which is more than enough for this MSI card with TDP of 60 watt or so. That card confirmed to work in Dell with 240 watt PSU.

5. SOCKET 775 WILL TAKE A Q6600

No questions, it will, but if MatthewMcLaughlin has Aluminum heatsink, his Q6600 would not last long enough to enjoy it, heat will cook it and might even take this MSI card with it, since it is very air tight PC case.

So, simple suggestion - Q6600 will fit - is not a good solution.

So best solution is half baked, I would say. MatthewMcLaughlin please do not buy new PSU or you will have nice looking paper weight.

Coming back to CPU heatsink. First, it is proprietary, so no aftermarket solutions are applicable here.

Aluminum on the left and Copper on the right, which one you have?

All Dell Optiplex QUADs have copper heatsink.

Your actual heatsink might look a bit different, but the idea is the same, just look for yellow parts inside the heatsink with a flash light, if you see vertical heating pipes - you have a copper.

If you have have Aluminum, well, it has to be upgraded to Optiplex 745 DT specific copper model, I am sure corndog1836 can find the proper one model number.

I am out.

MatthewMcLaughlin · Aug 6, 2015

So if I change my heat sink to a copper one my q6600 will be more likely to not overheat?

corndog1836 · Aug 7, 2015

http://www.tomshardware.com/answers/id-1845174/dell-optiplex-745-desktop-version-power-supply-upgrade-option.html

THE PSU WILL WORK.. got in a little trouble to get a definate answer..please reread this thread...

Kisianik · Aug 7, 2015

Oh well
I provided above the dimensions for the whole chassis/case, not for power supply and I provided a link to verify.
Dell PSU is actually much smaller, and see on my picture, where PSU cables coming out, it is on the side, now look at any standard ATX PSU - all cables coming out in the back, now come back to picture - do you see plenty of space in the back of PSU? I don't.
The only way to finish this discussion is:
@MatthewMcLaughlin: Please take a ruler or measuring tape and measure your PSU with case side panel open as shown on the picture, post those measurements here, it is not difficult to do job

corndog1836 · Aug 7, 2015

MatthewMcLaughlin :

Kisianik :

I checked that thread and COLgeek is sure of it...

But I AGREE.. measure is a sure shot.......... length x width x height ...

Kisianik · Aug 7, 2015

corndog1836 :

Come back to this thread and see how you worded your question

looks like the proprietary psu is larger than the atx to me from this thread....

Larger is the whole CASE/CHASSIS for which I provided 13.9" x 4.5" x 15.7", which is size of the whole case, sorry I was not completely clear on this, but there is a link to verify, oops

Edit: 13.9" x 4.5" x 15.7" is posted in this format length x width x height when PC is standing on the surface, if it is lying flat, dimensions would be placed differently
