FX-6300 Bottleneck R9 270's in Crossfire?

[xXxJumpinxXx]

I have an FX-6300, OC'd to 4.1GHz, and am wondering if It will bottleneck a dual R9 270 setup. I currently have 1 Asus R9 270, and am looking to add another.

If the 2nd PCIe X16 slot on your MB is not an X4 lane slot, it will be OK. The FX-6300 won't bottle neck the 2 cards. But the X4 slot will.

I have an ASRock 970 Exteme 3 R2.0
I says it has 2 PCIe 2.0 X16 slots, so I assume I'm golden and okay then !?

The 2nd pci-e x16 slot is only wired for x4 on that board, so you won't be ok.
You need a board with the 2nd slot wired at least x8.

I hate to be "that guy" but adding another R9 270 will get you only 30% improvement at most, you'll also have a hotter first card and frankly a lot of games are horribly unoptimized for crossfire so you'll end up switching off crossfire most of the time. I recommend selling off your R9 270 and get a 280x with the money you'll have then

I have to agree with Shadyhampster, you will see only minor improvement over 1 card with an X4 slot. Some games may even result in lower frame rates. Stay away from dual cards with the X4 slot. I speak from experience. I had dual HD 6850 in CF @ X16, X4. A bad experience.

I literally just bought the R9 270 on Friday, it has a 15 day direct in-store return/exchange policy. So My best solution would be to return this and exchange it for an R9 280 ? and forget about Crossfire, correct ?

Or Another route could be to replace my motherboard, and still go with 2 270's?

Cost-wise, since you can still get a refund, would be to go with the single R9-280.
