Can 4770K Work With Z97 ?



If you're going with SLI, you can run the cards in x8 modes. x16 isn't needed for each card. It is faster but the performance/cost ratio is terrible.
 


Actually, the only way to get x16 x16 on a z97/z87 motherboard is through the use of a PLX chip, which is almost always SLOWER for 2 card setups! PCIe 3.0 x 8 is absolutely heaps of bandwidth for any graphics card. While going to 16 lanes gives the card more bandwidth, it requires the PLX chip which introduces latency and benchmarks consistently show a (very small) decrease in performance.

Now if you wanna go 3 or 4 way SLI on Z87/Z97 you've go no choice but to go with a PLX mobo, but for two card setups it's worse! Don't do it?

OP, maybe you could describe in a bit more detail what the problem you're trying to solve is? It'd be real shame to spend all that money on a new motherboard to get no improvement, or even slightly worse performance. And I think that's exactly where you're heading at the moment.
 


Nice to know. I only did a quick glance at the motherboard selected thinking it was a PLX motherboard. Now that I've checked again, it's not. Do you have an article showing the benchmarks and analysis?
 


I'll admit that I've just had a hunt and can't actually now find the at least two articles which I read (some time ago now) which showed pretty consistently that there was a very small (like 1-2 fps) penalty going through the PLX switch. I've found a few forums where people debate it and some suggesting that the latency issue is really a legacy one (with older PCIe 2.0 PLX chips), so it's possible that I'm actually perpetuating a once-true-but-no-longer-true myth. If so, I apologise!

I do stand by my suggestion though that PCIe 3 x8 is plenty of bandwidth, no need to spend up on a PLX mobo.

OP... you still haven't told us what your current motherboard is? Does it not support SLI at all? Is that why you want the upgrade? If so, it makes good sense, but if your current motherboard has will run two slots at x8, you're going to get basically no performance increase by upgrading. Just want to make sure you're not throwing time and money down the drain is all.
