the graphic card that i have on my computer is not working so i was thinking about buying a new one. I have an ATI Radeon hd 2400. (the fan is not spinning at all) my motherboard is a gigabyte P35-DS3R. i was wondering if a ATI Radeon HD 4350 would be compatible. specifically the Diamond Multimedia ATI Radeon HD 4350 (4350PE512SB) 512MB PCIe x16. i dont have much cash to spend on the computer so i don't want to get a card that wont work for my computer.
