Hello, I woulkd like to upgrade my 9800gt video card to a better one as it burned out. It was working perfectly for me but now I need to replace it with a more efficient one. However, there are certain limitations- my power suply is 350W, and my motherboard is MS-7529(1.0a PCI-E), and finally my budget which is $100. About the motherboard I would like to ask if a PCI-E 3.0 card will work slowly with my PCI-E 1.0 slot. I would be really grateful if you could help me.
