4870 crossfire MB?

[magictorch]

Hoping to XF 2 4870's and am looking at these 2 boards: X38 P5E or X48 Rampage. The rampage is obviously a better board although it looks identical but I don't know if its worth the extra money once shipping and taxes are factored in. Im only planning on running at 475FSB daily. Plus could always flash the bios to rampage

I had been looking at the P5QE deluxe as well (sameish cost as P5E more or less).

Any help with choosing would be appreciated.

EDIT: Im going to get the DFI X38 T2R and go in at the deep end--not impressed with that metal on the asus boards but that DFI bios is gonna hurt

From what I hear the X38's seem to tap out at about 440FSB.

[magictorch]

only around 440FSB even with a 65nm core2? Thats not very good and worse than my basic P5K-E. At least the P45's have more potential with FSB but their "overall" performance needs some work.

So hard to choose a crossfire board for around $200

P5Q is probably the way to go @ that price.

Yeah, but there are those bottlenecking rumours with the P45 and Crossfired 4870s.

Just saying.

Yes I really liked the look of P5Q but decided to up my budget and bought a DFI T2R X38 on sale. Actually worked out at a similar price to the P45 P5Q deluxe. Its not supposed to be the easiest board to work with but it will force me to learn a bit more about overclocking than the other options. Plus I really like the layout too and the included northbridge tower.

I have the P5e. I'm not overly impressed with it. it was awsome getting to 420 FSB, but i cannot seem to get it higher than that, at a stable OC too.. 4.2 was difficult.. I had to raise my vcore up a lot, way more than i should have, and in cpuz it was showing my vcore to be 1.138 as ooposed to 1.4126 weird. I got it for christmas though, so not complaining ;) I would probably get a different motherboard if i could take this one back.

Edit: my cpu is in my sig

Thanks for the link zlojack, Well well well, I had originally agreed with SKY about 16x having little to nothing performance over 8x, but this review seems rather interesting. Most games the P45 managed to stay close to the X48, but quite a few games does it take a beating.

I was just looking at 2 Asus boards, the Asus Maximum Formula (P45) and Asus Rampage Formula (X48) which are really very similar to each other. Damn back to level one in choosing a X48 chipset.
