Asus Motherboards

Hi Asus_Za

i'm very confused about ASUS pricing and Z68 motherboards

I want to get a medium level motherboard with SLi but the naming and pricing is confusing to say the least. Also the Sli is twin 8X and not twin 16X which I'm sure will bottle the two medium range cards I aim to get.

Thus far my new sytem will look like this:
TX 750 watt
Asus Z68 mobo with SLi
8gigs Corsair Vengeance RAM
460 Sli/560 Ti
I7-2500K/I5 depending on budget
Hyper 212+

Have a look at any of the Republic of Gamers boards that end with the -Z Suffix or a normal product starting with P8Z68, that means they are the z68 variant of the board. Then just check if SLI is listed under the features.
So this:Prophecy.co.za - ASUS Maximus IV Gene-Z LGA1155 Dual-Channel DDR3 SLI/CrossFireX
Or a non RoG product such as this: Prophecy.co.za - Asus P8Z68-V LGA1155 Dual-Channel DDR3 (New B3 Sandybridge) SLI/CrossFire

Any input into the 8X switch for PCi-E?

Think I'll get the Asus P8Z68-V. Looks spiffing.
I spoke to Asus at rage and they said they are now covered for lighting which is excellent.
I can't be asked to prat around with some junk brand that doesn't provide good support.

Edit: I'm not a fan of named motherboards like Gene or Rampage.

IT shouldn't be much of an issue. According to these guys Intel Core i7-2600K and i5-2500K Processors Debut - HotHardware It shouldn't affect your performance at much at all.
Here is an older article from Tom's Hardware showing how x8 and x 16 affacets a gtx 480 SLI setup.
Here is another article showing real world performance: HARDOCP - Introduction - GTX 480 SLI @ 2560x1600 - GTX 480 SLI PCIe Bandwidth Perf. - x16/x16 vs. x8/x8

lol, well i have the gene-z, and let me say, i love it. Yes its M-atx, so its small, but single GPU solutions its really great.

As for the 8x sli bottlenecking, on 560's you wont even notice the difference. I think there might be a >5% difference on like 2 GTX580's heavily overclocked.

I have 2 x 480 GTX`s in SLI on my P55 and it runs without a glitch. My score in 3dMark is about the same as it was with my X58 setup running at dual x16 PCI-E
