Sapphire Radeon R9 8GB 295x2 for sub 600 bucks, tell me WHY NOT to buy?

Solution
The 295x2 only has 4gb of vram and depends on crossfire profiles for performance. I would spend a bit more for the 980ti. You would get more vram and no muti gpu hassles.
Reasons not to:
Massive power consumption.
It is Crossfire on a single card so while some games will get the full benefit others will get less and some none, so it's not a very stable solution.
Right now AMD are messing people around and not releasing updated CF profiles and drivers very quickly so it can take a while for them to release a CF profile for newly released games.
'Limited' 4Gb memory per graphics core might be a problem at very high resolutions or with masses of AA enabled.
Depending on the system case you may have some difficulty installing the rad.
Unimpressive 1080 performance (see link below).

Reasons TO buy it:
Massive performance when it works fully and you'll still have, essentially, a R9 290X even when there's no CF profile available.
Unless you're playing silly bu**ers at 4k rez or trying to run Skyrim with hundreds of high res addons 4Gb of memory is plenty for normal mortals.
If you're playing at 1440 res or over it's often faster than the GTX980Ti and can give even the TitanX a hard time: http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_980_Ti/
Cheaper that either the GTX980Ti or TitanX.
Unlike the GGTX980Ti it is actually available.
 
Thanks Coozie, I read the entire link and in the Summary, the writer suggests the 295x2 for BF4, which is primarily what I play.

Plus, the 295 is still cheaper than the 980 ti 6 gb.
