Haswell-E worth upgrading from ivy-bridge?

ambam · Sep 30, 2014

Would the latest iteration of the Core i7 processors be worth upgrading from my 3770K?

I use my computer mostly for gaming, would there be any noticeable improvement?

For one card rig no ! For SLI/Crossfire we must wait and see . i mean for gaming purposes .

I don't think it is worth upgrading for gaming as most games are gpu intensive rather than cpu intensive. Plus your cpu is quite good already for games.

Even when games eventually support hyperthreads properly, 3770k will still be good. There's little reason why you should go for more than an Intel Core i5 or AMD FX 8xxx at this time though.

Another question I had was whether my 3770K (@4.0GHZ) and Z77 motherboard would bottleneck two GTX 970's in SLI.

My motherboard only supports PCIe 3.0 x8, would that hold the GTX 970 back?

No, x8 provides more than enough bandwidth.

I advise that you keep your i7-3770K; gaming wise you most likely will not notice a difference. Upgrading to the next generation/Haswell-E would also require a motherboard upgrade. Your i7-3770K is more than satisfactory for all current games, hence I would keep your Ivy Bridge CPU.

However if you want an upgrade, you could wait for Skylake in 2015 (or beginning of 2016) which will introduce 6-cores on the i7 has standard, with Hyper Threading. A Skylake CPU should also cost less than a Haswell-E processor. Skylake will also utilise another motherboard socket, 1151 and will bring DDR4 into the mainstream market.

Of course all the above is purely my take on it, you're free to upgrade whenever you desire.

All the best.

Icaraeus :

PCIe 3.0 x8 has the same bandwidth as PCIe 2.0 x16 am I correct?

ambam :

You should be right . Btw , i would keep 3770K . The mobos for AMD FX 8350 has only PCI-E gen 2.0 but so many people get that CPU . Gen 2.0 x8 and x16 are still alive Look at the benchmark below . The test system had i7 4770K . SLI 970 nearly doubles the performance , this means that x8/x8 gen 3.0 is enough for SLI/Crossfire .

So the only thing that will push a PCI slot to it's bandwidth limits is a high-end dual GPU card like the Titan Z?
