I'm building a gaming PC, and I'm looking for a motherboard that will allow me to use my i7-2700k and up to three GTX-670s without being bottlenecked by low PCI bandwidths (4x). I've already bought the i7-2700k for about $250 and I'm trying to future-proof my new system as much as I can so I can play any future games without having to build another entire PC.
With this in mind, I'm considering the ASUS Maximus IV Extreme-Z, since that allows up to 3-way SLI in 8x, 16x, 16x, modes, is supposed to overclock Sandy Bridge CPUs excellently, and can be had for reasonable prices (goes for about $200 used online).
Are there better suggestions for getting the most out of my CPU/GPU combination for around $200, or is this a good MB? Thanks!
The newer PLX Z77's only work in 3/4-WAY with an IB CPU (PCIe 3.0), and will ONLY work 2-WAY SLI with any SB (PCIe 2.0) CPU. Examples that won't work 3/4-WAY with SB but work with IB:
Gigabyte G1.Sniper 3
EVGA Z77 FTW
ASRock Z77 Extreme9
ASUS Maximus V EXTREME
ASUS P8Z77 WS
ASUS P8Z77-V PREMIUM
