OK I found similar one for Optiplex 755 line up.



If you have Mini Tower, first from the left, tell us your budget, for stronger cards power supply upgrade would be required.
The best card without power supply upgrade for Mini Tower would be Sapphire 7750 2 GB http://www.newegg.com/Product/Product.aspx?Item=N82E168...
With power supply upgrade - your money is the limit, well size a bit as well (length of the card).

Also, correct yourself - there is no Optiplex GX650 in Optiplex family, the closest one is GX620, so which one you have?

I hope you can squeeze $100 plus shipping and get above mentioned card in store - this is the best without upgrading power supply for gaming, there are cheaper ones, but they ok for general use like watching movies and similar.

So?

UPDATE

Unfortunately no card that is more than 7.5 inches long or 2 slots wide will PHYSICALLY FIT inside the case - it was found that only single bracket video card can fit due to BTX MOBO, where card internals facing upward towards PC internals, not ATX, where dual card design is blocking another PCI slot by facing downward.

If you prefer the card with beefier fan, then the length of the card must not exceed 7.5 inches, otherwise only "skinny" single bracket, single slot cards can physically fit.

Pictures below will prove my point.

View shows no room for dual bracket



Single bracket only, or you have to cut dual bracket in half



Here you can clearly see only single place for the bracket



Visual explanation



7.5 inches explained, also shown "obstacles"



This is the picture of actual "skinny" single slot video card (not sure which model)- perfect, "glove" fit.



So, I found 2 GDDR5 7750 cards (GDDR5 is better than GDDR3, even if GDD3 offers 2 GB RAM), which confirmed in reviews to fit Optiplex gx620, 745 and 755 cases (the difference between those models are different processors).

Skinny, flimsier in terms of construction, completely single slot XFX 7750 http://www.amazon.com/XFX-DisplayPort-PCI-Express-FX775...

A bit beefier cooler, not as skinny, more durable in construction PowerColor AX7750 http://www.amazon.com/PowerColor-AX7750-1GBD5-DH-Video-...

I cannot say which one of those 2 is better, both are good and got less bad reviews related to structural build.
I saw recent recommendation regarding drivers "Changing to the just-released AMD catalyst 13.2 BETA driver improved performance noticeably in just about every game" posted 03/05/2013.

If you had previously NVIDIA card or NVIDIA chip - drivers have to be completely uninstalled prior to installing ATI card.

This is it.

P.S. If you insist to go with cheaper card, let me know, however any gaming would safer tremendously with cheaper card. Note, power supply upgrade is not necessary here.

Wow thanks for such a complete answer like that ! So basiclly all the cards you showed me in these (2) links are compatible ?

But i feel like these cards might have too high performances for the optiplex, am i wrong ? Because the PC itself is pretty weak
