I can exchange my "2.5 year old 4890" + "120$" with one "EVGA GTX 570". but I'm having second thoughts because my CPU is core2Duo 8400 and I'm afraid I cant get the performance I desire because of possible bottle-necking of my GPU.
And if the deal takes place, am I going to need to upgrade bios?(EP35-DS3L)

no need to upgrade the bios but your e8400 will bottleneck the card. you can oc your cpu to reduce the botttleneck effect
