Optiplex 755 DT - BTX motherboard, do you still have original case, the problem with original case is - you need low profile cards only, regarding Q6600 I need to check, very possible. I know only GTX 650 low profile will fit, nothing above.
If there is a way to mount this card in ATX case, there is a limitation by the length of video card - it could not be longer than 7.5 inches.

Do you have any other motherboards availble?

I was going to place it in an ATX case, that is possible right?? My question was basically what was the best gpu for gaming this mobo would support??

But it's ok since i think my money will be better spent building a new pc then trying to revive this one. I'll just scrap the hard drive and anything else i can use for my new pc. Thanks for your answers.

I have already answered about your CPU & GPU.

And ATX case can be used for both ATX & Micro/Mini-ATX based mobo.
 
Technically speaking, there is a possibility to use PCIE card riser to fit larger card, need more time to find more about it, the riser itself is here http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=bsd&cs=04&sku=430-2597&dgc=SS&cid=259365&lid=4645714&acd=12309173085460814
GPU choice unfortunately depends on power supply, you have only 280 watt, so only AMD 7750 low profile will work. Power supply is not upgradable in the original case.
However, it is not ATX board, but BTX! So standard ATX based cases not applicable here!
Answer regarding Q6600 - it will work here, it was originally sold with this!

Answered you on very beginning. Your CPU is supported but not GPU. That is the end.
 
OK, I am going to throw final ball here.
First, lets examine what Dell says and what users say.
Example 1. My Inspiron 570 maximum CPU upgrade per Dell is Phenom II x4 945, it is official. I happened to be the first documented user to attempt to install Phenom II x4 965 BE, and it works, now no one question this fact and many people follow my steps, despite the fact that this chip is not "supported", but it works! Second, with the same Inspiron, official RAM size is 8 GB, well, one user tried and got 16 GB working, I followed and I have 2x4GB working now, can upgrade to 16 at any moment, not officially supported, but working.

Example 2. Optiplex 755 SFF, a bit smaller than 755 DT (futured in this post) and has 275 watt power supply (755 DT has 280 watt). PCIE is rated on motherboard same 25 watt, however, I serached everywhere and guess what, there is no official Dell statement about PCIE 25 maximum rating of 25 watt, so this looks fishy to me.
So, brace for impact and keep reading, this is how miracles are born.
This is life example of Optiplex 755 SFF with Sapphire 7750 low profle card - http://en.community.dell.com/support-forums/desktop/f/3515/t/19349759.aspx?PageIndex=4 if you don't believe me, read it.

And finally, example 3. This is from official Dell upgrade site.
The Visiontek® Radeon 7750
Manufacturer Part# : 900574
Dell Part# : A6523076

Can anyone attempt to find any arguments here?
This is called search. I stay behind my words!

So, to OP, yes you can upgrade GPU as well, I know it is too late now, but if you want, you can still to do so! Proven, works!
