1. 4870 ~$145, 4890 ~4$190
2. Buying one card now but want ability to crossfire down the road
3. looks like 2 x 4870s require a 750W PSU and 2 x 4890 will require a 850W PSU
A. Is that PSU requirements assessment correct?
B. How much better is the 4890 than the 4870
C. Given my build, will i tell the difference between 4870 and 4890
D. If that $ and PSU assessment is correct i will have to spend an extra ~$45 for the 4890 PLUS $ difference for larger PSU... is that correct?
Thanks, build info below from previous post.
