Thanks a bunch for the input guys. I'm hunting for the 4870 as we speak. I'm pretty much changing my whole setup right now realizing my first post is a disaster lol. Glad I posted here.
I'm pretty much torn apart between the core 216 and the 4870. Based on the price, it looks like the 4870 pulls ahead, but the core 216 does perform better in some games that I'm interested in.
I'm not much of an advocate for dual-GPU cards, but that card looks pretty sweet though, even if CF doesn't work I get HD 4850 performance, which is still pretty acceptable
EDIT: Wow the HD 4850X2 is cheaper than two HD 4850's
