有支援Crossfire的遊戲，理論上295X2的效能會比較好，但非常倚賴驅動程式的更新
像剛上市的遊戲未必能馬上使用Crossfire，這樣295X2就跟一張290X沒兩樣

像我買不到Fury X 我會等R9 NANO CF
雖然加起來可能貴一點
但功耗好像會差不少(NANO 175W)
又"聽說"接近或超過290X的效能(不知道以什麼來算 說不定是非遊戲運算)
感覺好像不錯 等等看NANO評測再下手也不遲嘍

如果FURY X買得到，那當然以FURY優先，那是不用懷疑的~~

物以稀為貴，之前小弟也講過FURY X不是賣到沒貨，而是沒貨可賣，很多合作
廠商根本拿不到貨源或數量相當有限，這情形恐怕要到年底才能逐漸緩解，並影
響次級FURY與NANO出貨，目前情況下，FURY X價錢遠高於官方定價，也
是沒辦法的事...


遊戲性能上可參考TPU，4K下FURY X約295X2八成左右，每瓦效能遠優於
295X2，但如樓上luke兄所講，CF會因遊戲支援度產生”效能振盪’的情形，其
振幅必高於單卡，這是一定要注意之處

另295X2為GCN 1.1，FURY則至少為GCN 1.2以上，其差異可參考以下
http://www.kitguru.net/components/g...cture-revealed/

• One of the key features of the third-generation GCN is updated instruction set architecture (ISA). While there are not a lot of details available at the moment, expect the “Tonga” and other GPUs based on the GCN 1.2 to support certain new capabilities that improve its overall efficiency when it comes to computing.

• Another thing featured by the new GCN is yet again improved tessellation/geometry processing performance. It is unclear whether AMD redesigned its geometry processors in general, or just increased their amount, but tessellation should work better on the GCN 1.2 compared to previous-gen GPUs.

• To reduce requirements for memory bandwidth and improve performance in high resolutions, the GCN 1.2 supports delta colour compression. The latter is an image compression technique that encodes a row of pixels by replacing their colour information with values that represent difference between subsequent pixels (e.g. if one pixel in RGB format is 255:0:0, the other one is 255:1:1, the third one is 255:2:0, then with delta compression the sequence can be represented as 255:0:0, 0:1:1, 0:1:-1).

• The GCN 1.2-based GPUs will also feature a new multimedia engine – which comprises of universal video decoder 6.0 (UVD 6) and video encoder engine 3.1 (VCE 3.1) technologies – as well as a new high-quality scaler for video. There is no word about support for ultra-high-definition (UVD) video codecs, such as H.265/HEVC or VP9, so it looks like the new GPUs will not support them.



DX12 VRAM STACK的問題，如果API直接支援當然很好，但恐怕沒有那麼樂
觀，其硬體層級可能需要遊戲商去介入才有辦法，目前尚不明朗

Fury X Fury + 1

不過目前太難搶到現貨了,要多跑好幾家.

建議是Fury Nano/ Fury, 至於Fury X...看來不是落在P/W的甜點, 更不要提295等級的吃電怪獸.
只是Fury X 生吃都不夠了, 還想曬干等Fury Nano/ Fury 的機率更低...

現在選295x2很快就後悔 那個耗電/熱量 不是一般人可以接受的..

沒貨就等 搞不好NV降價或者提早出新卡
Fury一定是優先鋪其他地區 我問了一下 他們都說直接訂就有

FURY目前產能相當糟糕, 甚至有些測試網站拿不到FURY來REVIEW, 這情形相當罕見, 除了
FIJI GPU的超複雜結構, 加上HBM VRAM, 之後送到韓廠進行整合(PACKAGE), 都會斷送不
少良率, 雖然合作廠商諸多抱怨, 但良率問題恐怕不是短時間內能解決...

295X2的唯一救贖就是送修升級而已。

如果可以

建議等明年的新卡吧！

反正都是等…
