2way CFX/SLI scale much better than 3way CFX/SLI.

$649 for nano? Might as well get Fury or Fury X. Nano will get throttled once it past certain temp/power limit no? What the hell is AMD thinking? I doubt it can run at full speed 24/7 during gaming. That price for a mini itx gpu not worth it especially if it will get throttled in some way.

Probably because
1) It wont perform like fury x. SOS:http://www.techpowerup.com/215529/amd-radeon-r9-nano-core-configuration-detailed.html

2) Less VRM should mean less BOM. That just the VRM no counting the amount of other smaller chips in nano pcb. FuryX using 6+2 PHASE VRM but Nano using 4+2 only. Potentially means even worse at overclocking than fury X.

Its like saying Myvi with no aircon should be priced higher than normal Myvi with aircon because its a niche market that someone somewhere dont need the aircon. Maybe im salty. Been saving up to get it just to be slap in the face now that it priced similarly with fury X. Now that 1USD~MYR4.2, i should have bought FuryX when it launched and not waiting for this nano.
