OK...first off I know that the 4890 CF is faster at stock speeds. I know this.
Now, I'm thinking of selling my 4890's to fund the purchase to the 5770 Crossfire. Why? DX11, lower power, and lower heat.
Performance isn't a big deal, I'm not looking for a performance upgrade more than I am a features upgrade (DX11, lower heat, power, etc.).
My question is how well can the 5770 perform overclocked?
I see that in all benchmarks that a 5770 is about on par with a 4870 with the 4890 being a good margin faster (10-20 fps faster in general). I also know that due to lower power and heat that they can overclock quite well.
Ive read in reviews that the 5770 also scales a lot better in Crossfire than the 4890, no benchmarks though, just reviewers saying so. Also, I see that the 5770 Crossfire is a good margin faster than a single 5870...so I would like to stick with Crossfire instead of a single card. Also Eyefinity is only possible on 2 cards, no?
