Optiplex 745 MT vs Graphic Cards - GT 710

Hi, I would like to ask for some advice for find the correct graphic card to upgrade my Optiplex 745.

I’ve read a lot of nice advices from SpeedStep, but I could not found a solution yet.

I still using my old dell 745 MT.

Intel Core 2 Duo E6300 1.86Mhz, Q 965 – Bios 2.6.4 (not updated), W7 Ultimate Ed. X64, 2 seagate HD 2TB each.

I’ve already upgraded a power supply to 500w and a memory to 4 x  2GB DDR2 667 (8GB total)

I purchased a Intel E7500 but a friend told me that it is not compatible. (never tried to install)

745MT works very well, exception for a Radeon x1300/1550 card

Basically I use my Desktop to work with Adobe’s programs (Illustrator, Photoshop, InDesing, etc)  and to watch a lot of movies :)

I’ve read about 745 PCi-E’s  limitations (version 1.0, 25W power socket, etc)

As I need it to work and to watch movies,  I prefer a fanless video card.

My doubt is about compatibility and space. There are 2 big capacitors in the MB next PCI’s space

My selections are

1 – Zotac GT 710 DDR3 2GB Passive ( Looks like it fits)
