Hi, I am using a Gigabyte Motherboard 81865GME-775-RH (rev 2.0) along with 512 MB DDR RAM and Intel Core 2 Duo D Processor. I want to upgrade to a new Graphics Card but don’t know about the compatibility issue. Can anyone suggest which 512 MB Card I can go for? I will also be upgrading the RAM to 2 GB(DDR). Thanks.
