i7 4790k, gaming专用主板，玩Simcity, Sim4之类的游戏，应该选一个好显卡，还是
两个次好的显卡？
我在看Sapphire R9 290 Vapor-X，但是有人说买两个280可能更好。
这个机器用来看看片，玩玩游戏。

一个是好，可是那是在streamer数目跟两个加起来可比的情况。
一个290只比一个280x多一点点streamer，比两个280x交火肯定差老鼻子了。

"Conclusion
First of all lets talk about prices. Let's consider that the two R9 280X
together cost 422 Euro. Compare that to the 396 Euro you'd have to pay for
the cheapest reference R9 290X we can find. Therefore this one high-end card
is is about 7 percent cheaper than the two mid-range models.
To dive a bit deeper into the results, we start with performance differences
in 3DMark graphics score where we see that the CrossFire of the two R9 280X
is between 39 and 41 percent faster than the single R9 290X. In the next
theoretical test we ran, Unigine Heaven, we see that the two R9 280X's are
on average 17 slower than the R9 290X. In case of games it turns out that
for example in Sleeping Dogs one the one card is about 18 percent quicker
than the two cards in CrossFire. A closer look at Call of Duty Black Ops 2
shows the other end of the scale, where the two R9 280X's score 24 percent
better than the single R9 290X. In this case we see a rather huge variance
in the test results.
Overall the two R9 280X cards are performing really well and there is no
doubt the two of them are seriously quick, actually, on average they're 10
pecent quicker than one R9 290X. But the problem is that the average value
is not even telling half the story. It turns out that in quite a few games,
the two 280X cards together are slower than the one R9 290X, which make
performance rather unpredictable. Other than that there is power consumption
. In idle the power consumption of our test system is almost 70 percent
higher with the two R9 280X then with one R9 290X and under load conditions
the setup in CrossFire can almost be used as a heating system. Concluding,
it can be said, that under certain circumstances the two R9 280X cards are
quicker than one R9 290X but if you want to invest your money in an as
sustainable way as possible, then we'd recommend you to buy a single card
and even save a few bucks. "

只生一个好。除非你像我一样搞GPGPU。
话说，我觉得现在最好的投资是：
1）6GB版本的280X。
2）早期版本的290，可以刷BIOS开核成290X。
