Ok im stumped here, question is can you go SLI with a ATI crossfire board?

Asus P5q-e and the Biostar Tpower I45 these both are ati crossfire boards but could you go SLI if you wanted?

Tried googling info on this but came up nothing.
 
You cannot SLI with an AMD chipset, and you cannot Xfire with a nvidia chipset. there are a few intel chipsets that will do both though.

Dang that sucks heh, does anyone happen to know is the nForce 650i SLI chipsets decent, and if this board up to par to the 2 I showed up top Asus p5n-e?

Decent and not up to par. The two Intel chipset motherboard are better in terms of stability, quality, reliability and cooling than any Nvidia 650i or 680i motherboard. And as been said before, you cannot use a Crossfire setup with an Nvidia chipset.

Just some info on SLI / Crossfire: It's absolutely not worth considering if a) you're gaming at a resolution under 1920x1200 (as you'll see no performance benefit over a single card,) and b) if you plan to buy one card now and another later. SLI / Crossfire as an upgrade path is usually a very poor idea, as by the time you're ready to get that second card, a new single card solution will likely be available that will outperform two of your older cards in tandem. Furthermore, there really is no cost benefit to the SLI Upgrade Route, as any additional cost in getting the new card can be easily mitigated in most situations by selling the original. By avoiding an SLI / Crossfire solution when it will not be of benefit, you gain a cooler running, simpler to maintain system and more importantly, access to a much better (and broader) selection of motherboards.

Thanks I will keep that quote in mind and do some more research on this. ;)

I just wonder about this ddr2 800 and why is it that is it not slow? It confuses me and I found info on 750i chipset wonder what big diff is from the other.
 
A friend bought a 750i evga three weeks ago, it's fine. I recieved my 790i a week ago last Monday (June 23) and that is fine as well. The only thing I did was update to P05 bios for the 790i. It's a production 3 board. That's really all I can speak to in terms of direct personal experience.
 
Thx mega for the tip and info on that, scratch my Q on the ram nevermind about that got confused with the numbers.

As for that board the question remains does PCI Express "2.0" really make a big diff? I know even if a vid card supports 2.0 it can still run with out it.

I had found a board from asus known as the p5n-D not sure if its decent it seems good. Its almost exact like the p5n-e version of the board but just for SLI.

No, PCI-E 2.0 doesn't matter yet, you just make sure they are full 16x. A couple people got nailed on some Intel boards that drop to 8x/8x mode in xfire. These boards are limited at high res with the 8x.

Asus quality has been a little suspect lately, and I know they have been a little slow with bios updates. No real experience with asus yet. Looking at the newegg reviews, the evga 750i seems superior (especially for the last two weeks). I'd stick with the evga 750i, lifetime warranty - unless there is something specific with the asus board you need.
 
I know there are a few runnin' around the [H] with Skulltrail setups, just gotta find them.

Is it true that the EVGA boards are having problems with video corruption problems and some people it works fine and others its really bad? I also noticed someone asking you about it I would assume? So I am guessing theirs a new bios update that fixes this?

There has been a patch released, rolled into the bios, not sure which version. no video corruption. 7xxi boards.

The 750i arrived, fired right up with the q6600. No overclocking, it's not for me. That would be 3 for 3 on the evga's.
