Must Read Tweaktown Article if you want to do 48xx in Crossfire: P35/45 vs. X38/48

post #1 of 10
Thread Starter 
It seems like more than a few people are interested in getting two 4850 or 4870 cards now that they've (more or less) lived up to the hype.

But Tweaktown just posted an article comparing Crossfire on a Gigabyte P45 vs. X48 board, and the x8/x8 configuration can be severely handicapped at high settings.

Glad I decided to buy a Maximus Formula.

Only question now is, how much of a performance boost will the 4870 bring?

Argh, I wish this was posted before I went out and got a P5Q. Oh well; it's not too much of a performance loss.

I tried posting as soon as I saw it, too.

If you're not doing really high settings and resolutions it might not hurt too much.

You could try overclocking the PCI-E bus for some extra bandwidth.

Yeah, I'd guess it would be, depending on scaling.

Hehe, if that HD4850 with HD3870 CF rumor is true, I wonder if it would be limited too much to be good?

Aren't you guys forgetting something? The HD 4850 is new and the driver have not been fully optimized yet... Would be better if they bench the HD3870

That article comparision only affects people running 30-inch monitors with 2650x1600 resolutions. The performance hit on resolutions under 2650x1600 is marginal.
