Hello, this is deepanshu, i own a nvidia 9500 gt card 1 gb running on my gigabyte ga-g31m-es2l motherboard. i wanted 2 upgrade my pc by buying a new zotac gtx 550 ti whose spec is it is GDDR5 and is pci-e x16 2.0 .My mobo has a pci -express x 16 1.1 slot only. i dont wanna buy a new mobo now, only want the new 550 ti. so can you please tell me if and wat will be the compatibility issues i may face and will there be any performance loss by runnin a pci e 2.0 x16 in a pci-e 1.1 x16 slot. And can my mobo support ddr5 card?
