this aint how this site works. you could just be an email scammer... if you want a reply then come back and get it then say thank you... if you cant do that then happy days. dont let the door smack you on the way out.
as for you request... there are no cheap sm3 cards, they went out of production 4 or more years ago. now we have sm4 and 5 both are backwards compatable. but are unlikely to fit in your motherboard unless you have pci-e 1.1 with an nforce 450 chipset as minimum. and the killer is they can be had for as little as $30 for hd video cards and $70
for entry level gaming.
