I understand the nVidia 590 card can run multiple monitors. If I am building a new computer with the 990i CPU, will I benefit from dual 590 cards? 1 monitor is my 2D cockpit panel and 2nd monitor only shows the FMC and throttles. Can you even run dual 590 cards? (enough room, slots, power etc?)I want maximum performance, but is it worth the extra $700?Please advise. Thank youPaul Gugliotta

If you are building FSX system, there is no benefit from 590, same as it was with 290. In fact, probably worse.You can run dual monitors from 580 the same way. If you want more, best is 2nd card from what I read...And oh Lord... why 990? You like paying too much? Beside 2600K will probably kick 990X's performance in FSX... as it does it most games.Only thing better: video-encoding apparently. Due to 6 cores I guess and more cache.EDIT: And 1366 socket is dying... 1155 *might* live a bit longer with upcoming Ivy Bridge.

Kostas is right. If you're building a computer exclusively for FSX, then you don't need a 990x. A more judicous purchase would be a 2600K or 2500K and a good cooler. Then OC to 5ghz.The only reason why I would consider the 990x is because, I can just drop it into my board. I can OC to 4.7 and gain some benefit in FSX and with other video programs. I would be using it for more than FSX.
