I have the HP h9-1130 phoenix desktop. I purchased a new GeForce GTX 650 card, thinking I'd be able to upgrade from the 1gb card it comes with to a 2gb card. Didn't work - never would get past the HP boot screen, when I installed the new card. Then, found the following on the HP support site:
Must select from one of the following:
GeForce GTX 550 (1 GB)
GeForce GTX 580 (1.5 GB)
Radeon HD 6850 (1 GB)
Radeon HD 7670 (1 GB)
Radeon HD 7770 (2 GB)
Radeon HD 7950 (3 GB)
So, makes sense why my 650 gtx card wouldn't work - my question is this - are there any more cards that might work with my computer - not sure if this list was the most up to date one available....thanks for any help!
