Best Crossfire/SLI Board for OC'ing?

post #1 of 26
Thread Starter 
I have pretty much everything on my dream build planned out. I am looking for the most COST EFFECTIVE board/Video Card that supports 2 or more PCIe x16 slots for either crossfire or sli. Apparently PCIe 2.0 isn't a huge improvement over 1.0/1.1, so it's not a big deal.

Fast RAM compatibility (Like 1066 DDR2) would be nice but not required.

It must be a good board for Overclocking (I will be using a C2Q6600 Processor).

The Video cards do not have to be amazing, nor do I want two. I just want a good card that will last me awhile with the option to throw in a second card later on.

Basically, I want the board/ Video Card combo that will best price/benefit ratio through overclockability and upgradeability.
For example: I don't want a $400 DDR3 mobo that will be worth half that two weeks from now, nor do I want a $50 Board that I will have to replace within a month.

Thank you guys.

I think I saw the DFI LP 680i for $99 in the deal section. Pretty sure you can 3-way sli with this board and being DFI will have alot of BIOS tweaking options for overclocking.

The 680i can't overclock a quad for :turd:

Either go for the DFI DK X38/48 or the EVGA 750i FTW.

Well... there's my 780i I'm looking to maybe sell. I know it's good for ~420FSB (my chip maxes out there.) It's like... 2 months old.

And if you have the time, could you please explain why you chose the boards you chose? There are other boards out there that I have seen for nearly half the price as those with what seems to be the same specs (1600 FSB, 1200mhz DDR2, 2 x PCIe x16, etc. Is there something that I'm missing that sets these boards above the cheaper ones?

You won't find a cheap X38/48 board, they just don't exist. The boards offer full dual bandwidth PCI-E2.0 slots. The HD4870 performs about 20% faster than the HD4850 according to the latest benchmarks. I highly advise it if you are gaming on a 24". If only on a 22" then two HD4850's is more than enough. A cheaper board would be the DFI DK X38.

Well, ok. (Other than faster PCIe 2.0) What is the benefit of having a X38/X48 board over a cheaper one though? Are those features really worth it?

As for the card. I will not be gaming on a 24", probably not even a 22". I'm most likely going to be using a 17" or a 19", and playing less graphic-intensive games like WoW. Sure, I may play some Crysis or other intensive games, but x16 anti-aliasing and full settings on a 24" monitor is something I really could care less about. All I want is a card that will last me a long time without having to upgrade.

Think of it like a car, I don't want a Ferrari, I just want a cost-effective car that doesn't require me replacing it too soon in the future.

That's basically your build right there, it's the most cost effective setup for a 1440x900 monitor.

X38's can run crossfire in x16 x16, which can give you a nice frame boost in most games. One benchmark I was looking at compared X38's and P35's I think. The X38 system averaged around 7 more FPS in Crysis if I remember correctly. I can dig it up for you if you want it.

This seems marginal, but when you're around 25-30 FPS (which you will be in Crysis with two 4870's), an extra 7 FPS can really make gameplay a lot smoother.
