I Have a Dell Optiplex 780 stock (as far as i know) and I wanted to get a better graphics card so I can play better games at higher frame rates. I was recently looking for some graphics cards on Newegg and I saw "PCI Express 3.0 x16" "PCI Express 2.0 x16" etc. I was just wondering what PCI Express graphics card should I use on my pc which has a PCIe x16 expansion slot?

I have the minitower:

Thank you!

You meant any small tiny cards?

THIS POST APPLICABLE TO MT (MINI TOWER) FORM FACTOR ONLY.

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

This is the other way to show my point

Here you can clearly see only single place for the bracket

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, in reality there are not so many cards, which you can place inside.

The best so far is MSI N750ti-2GD5TLP GeForce GTX 750 Ti 2GB 128-Bit GDDR5
This card will work on your power supply just well.

Today risers are hard to find (and explain their use), so I am trying to offer easy, Plug and Play, solution, when ever is possible.
What riser model do you have?

No, I don't have Optiplex, only Inspiron shown in my signature.

A, O the soft riser....

I though you have something similar to this

Those are the difficult to find ones
However with soft ones you can have a open motherboard solution, so no overheat, LOL.

I hope you upgraded to at least Q6600 and overclocked?

Aah, good job, but not good enough - you could overclock to at least 3.0 using BSEL/tape method, interested? And then use set FSB to possibly crank even higher?

That would be nice to start a new thread in respect to OP, otherwise it called thread hijacking

Just drop here a link.

In the new thread specify your form factor and motherboard model.
