I have the MSI 8800gt.It is an excellent card,and works well with AH.My system is close to what you will have.AMD 6000,4 megs ram,Gigabyte SLI MB, and 8800gt vid card.The 8800 gt is a large card,and takes up a pci slot.You will be pleased with you purchase,which by the way isn,t priced too high,at around $220,to $215.
