Hello All, So I have somewhat of a simple question. I will be building a new (long lasting, 5 year) gaming system soon and I would like to utilize two GTX 780’s in SLI. I know that, for most games now, I really would only need one GTX 780, but I only build a new computer every 5-6 years, and I want to make sure that I build something that I can still play the new games down the road on high settings. With the recent information about Ivy Bridge-E (http://www.maximumpc.com/leaked_intel_roadmap_reveals_new_batch_haswell_chips2013) and the release of Haswell and the Z87 chipset, I have come to the conundrum that I am in now. I know that I can SLI on the Z87 motherboards, but I would be relegated to x8/x8 (unless I get a motherboard with a PLX chip, but I want to stay away from that). I have read a bunch of the forums and review sites, that say that x8 PCIe 3.0 is the same as x16 PCIe 2.0, and that the difference between the 3.0 x8 and 3.0 x16 is not major, in today’s games. Also, that most GPU’s do not fully saturate the PCIe 3.0 lanes. Further, I know that I would be able to SLI on the x79 motherboard and I would be able to utilize PCI3 3.0 x16/x16. My motherboard/CPU set up would be: Asus Z87 Sabertooth + i7- 4770K v. Asus X79 Sabertooth + i7-4920K (or i7-4930K) So here are my questions: 1) Would the bottleneck caused (if any) by 3.0 x8/x8 be a big issue when gaming on a Z87 motherboard with 2 780’s in SLI, when playing today’s games on max settings? 2) Would gamming on a Z87 motherboard with 2 780’s in SLI run into some performance issues later on (2-3 years), and would these issues be noticeable? 3) Would the cost of an x79 motherboard and Ivy Bridge-E system be worth the ability to utilize PCIe 3.0 x16/x16? 4) Would the loss of the Haswell and Z87 features be worth it to go the X79 chipset? 5) Which one should I go for? **I really want to make sure whatever I buy now is correct, since I will not be upgrading for another 5 years.** Thank you in advance for the responses, and I apologize if this has been answered already.
