Opinion for Graphic Card #GPU

Hello guys,

I installed iATKOS L2 on my system without problems. All hardwares run perfectly except of my my graphic card ( ATI Radeon hd 3450 ). I decided to buy a new graphic card. So is there anyone who has idea about a graphic card for iATKOS L2? I searched a bit but I could not find the result. Or can you offer a compatible driver with iatkos if my graphic card has it. I have been trying for one week. I will be waiting your helps.

My system;

GA-G31M-ES2L Gigabyte Motherboard

3GB DDR2 Ram

ATI Radeon HD 3450 Graphic Card

Intel Dual Core Procosser

20GB IDE harddisk
