Hey guys,

Just had a question about this motherboard - http://www.newegg.com/Product/Product.aspx?Item=13-131-...

I plan to run two gtx 570's with aftercoolers attached(either the msi frozr or the gigabyte with 3 fans attached to the gpu).

But after reading the reviews on this thing there were a few users complaining about the pci-e slots being to close together and to not buy this board if you plan to crossfire/SLI?

Can anyone that owns this board with SLI/crossfire/2x decent sized cards, confirm or debunk this statement? As this looks like the mobo I want to get and would really appreciate the feedback!

The PCIe slots are spaced the same as every other MOBO out there, I've see this question a lot. So if it's a problem then EVERY standardized MOBO share the same exact problem. Dumber, if the PCIe were differently spaced then they would not line-up with ANY case -- they line up.

My only contention with the ASUS Sabertooth is it's a 2-WAY SLI MOBO period, and 'just in case' I would look to the ASUS P6X58D-E with 3-WAY support if needed later; plus it offers better power 16+2 phase vs 8+2+2 in the Sabertooth.

BTW - the top GPU will run hotter, the good news is the GTX 5XX series runs cooler than the prior GTX 470/480's.

Thank you jacquith, always so informative and concise with your answers!

I am strictly only planning to 2-way SLI, as 2x 570-s I think will last me about 2-4 years before I will end up building a new system anyways.

Would the power provided to the cards by the mobo present any noticeable performance changes, or overclocking ability? I never heard of the power phases, just that if it had 2x 2.0 16x pci-e slots then its good to go.

The ASUS Sabertooth X58 is a very good MOBO and you won't have problems OC'ing. Therefore, the power/phases are more than sufficient and actually I like the distribution of 8 to the CPU, 2 to the Memory, and 2 CPU VTT for OC'ing.

Yep, with 2-WAY GTX 570's you'll be fine and THEN some for 2-4 years on any HD Monitor.

Even though, until yesterday, I always recommend the X58 in 2-WAY+ SLI. The SB would really inhibit the GTX 570's with x8/x8 as per chart.



Good Luck! :)

I might be a bit confused, but does that mean there is no SandyBridge x16/x16 board? So the choice comes down to better GPU performance (x16/x16) with lower CPU (the older 1366 socket) or lower GPU (x8/x8) with SB (1155)?

Even the 'vague' SB + NF200 are found to be x8/x8; the description is if you read carefully - either PCIe_1 <OR> PCIe_2 are x16 the BUT is PCIe_1 <AND> PCIe_2 are x8.

Here's a good link -> http://www.evga.com/forums/tm.aspx?high=&m=120725&mpage... there was a very heated debate when I was telling the folks about the NF200 and that it would yield x8/x8...

The i7 9XX CPU are NOT going to be a bottleneck for ANY GPUs made in SLI/CF with x16/x16. I'm running mine at 4.6GHz 7/24, but even at stock CPU it won't bottleneck the GPUs. The X58 'chipset' and MOBO are superior to any P55/P67 MOBO, granted I like the SB CPU, and since I hate to choose -- I'll wait for the X68 or build off the X58 now. The above chart says it all.

Here's something I put together to aggravate some early P67 adopters, funny thing is it's 100% true:

I have a asus x58 sabertooth, i7 950, 6 gigs of ram, 1000w silverstone psu, and a gtx 590 and I still get crap FPS in COD black ops. I had a gtx 470 then I updated to the GTX 590 hoping that it would solve the problem but I barley got any boost at all. Any advice?
