Well, I was contemplating running a 3780 X2 for my new build, then SLI'ing 9600gt's, then this one, the 9800 X2. But for the price and performance, It's not worth it.
If real world results are like this on big reviews, and the price is about $200 MORE then a 3870 X2, this card won't do so hot. I'll be going to a 3870 X2. I haven't used an ATI since I had my 9800 back when HL2 came out.
Granted, it is the fastest and most BA card out there, it's about $200 more then it's competitor. And doesnt look like it provides $200 more in performance.
