I've got a Bfg tech 9800gtx+ oc that isn't really doing the job for me anymore. Ever since I started recording with fraps, my frame rates weren't all that great. I was thinking about upgrading to an HD 5870, but I recently discovered how much power the GTX 480 has over the 5870 as far as tessellation goes. I'm also wondering about which one would be better for futureprofing my system.
If you will buy an gtx 480 do worry about melting mobo bro its power hungry card ...rather go with the hd 5870 it's worth buying ...and if you want to sli get 2 gtx 460 and then see the power of this card.
But for single gpu hd 5870 will be ideal.
