road_dog never replied yet. Is your Inspiron 531 (AMD) from the same era his is? My daughter has the Intel version; an Inspiron 530 from the C2D 6600 era that works with just about any card I've tried as long as one manually changes the BIOS to PCIe. I can't see any reason those cards wouldn't work either. The new Maxwell-equipped GTX 7xx cards may cause some issues in some OEM PCs due to their new architecture. But older cards should be fine. At least that was my experience.
Thanks for your quick response
Clutchc. I'm not sure if my pc is from the era that you said. I have an amd dual core processor in it at the moment. I have done a lot of reading recently about the type of gpu that my motherboard will support and either a gtx650 or radeon hd7750. I think that the nvidia card is the better of the 2 . I don't want to go any higher than a gtx650 incase it damages my system. Unless I'm totally sure it can take a higher one.
Thanks for your help.
