Will an i7 920 @ 4ghz Bottleneck 2x 6950 2gb?

post #1 of 7
Thread Starter 
BF3 is worth crossfiring for, which is exactly what I'm hoping to do. I'm just wondering if my i7 920 @4ghz (191x21) will bottleneck a second card.

It has also occured to me that my Ram may be an issue. It's running at ~1560mhz IIRC because of the multixbclk setup.

Let me know what you guys think! Thanks

Wonderful.

Also, would there be a noticeable performance gain if I were to throw an i5 2500k into the equation?

Nope, no bottleneck. You may gain a couple fps w/ 2500k.

Just go Xfire for now. Wait 6 months for Ivy to come out and see if that has a good increase in gaming performance over Sandy. Your 920 will be fine for 2 6950's. I only left X58 to Sandy because I have 3 Gtx 480's and my 980x was bottlenecking in surround resolutions like 5850x1080. I gained like 20-30% increase moving, but you may only see 5% gain which really isn't worth it.

the only real allure for you to go SB would be the drop in heat and power consumption.

You are fine. As a note, I'm playing BF3 at 1920x1200 at completely max graphics with just a single 6970 - I'm sure you could do the same with just one 6950, especially if you unlock the shaders.

edit: also, I don't think your ram will be a problem either - I was at 1420MHz XMP configuration.
