What is the best

[admin89]

GTX 780 is on par with GTX Titan but 780 is cheaper ... (release date for GTX 780 : May 23 2013)
i5 3570k @ 4.2GHz + Asrock Z77 Extreme 4 + GTX 650 + Seasonic S12II 620W + 2x4Gskill Ripjaws + Intel SSD 335 80GB .... = 800$
i7 3970X is not much better than i5 3570k since Dolphin doesn't care about Hyper Threading . You will have overclock both i7 and i5 anyway -> i5 is a better choice
Swap GTX 650 -> GTX 780 , we have 1500$ build

3570k will run most games just fine.
Define "the most demanding games on the Dolphin emu". Which games exactly?

It is not on par, it is slower

[admin89]

Specs comparison ....
GTX 780 is pretty much a GTX Titan LE (slimmed-down version of Titan , Titan LE does not exist btw) , GTX Titan is faster of course but GTX 780 is pretty close to the titan in terms of specs
Pricing is about $645 USD (Nvidia has announced this )

Yep, you're right.

GTX 780
3.97 TFLOP/s
288.4 GB/s
3GB

GTX Titan
4.5 TFLOP/s
288.4 GB/s
6GB
It looks like they both use the same chip (GK110) and the same memory bus (384 bit GDDR5 6008 MT/s). The difference is that out of the 16 SMX units (basically the "cores" of the gpu) on the chip 2 are disabled on the titan and 4 are disabled on the GTX 780. But the GTX 780 has slightly higher clock rates giving it the same TDP (250 watts) but slightly lower throughput (3.97 TFLOP/s). They will likely end up using the same cooler since it will have the same TDP. Since larger chips with more SPs can deliver higher performance per watt by using lower clock rates and voltages combines with higher ILP/TLP the titan achieves higher performance with the same power consumption.

Nvidia is doing this to boost yields since their massive GK110 chips must have terrible yields (die size is 561 mm^2 which is crazy) which allows them to lower the price and still offer something faster than the GTX 680 to fill in the gap between it and the titan. Meanwhile they can start selling all of those partially defective GK110 chips that they were throwing out before so it's a win win. It's too bad that the only way to feed such a powerful GPU with enough memory bandwidth is to use a large, expensive, and power hungry memory bus design to achieve the necessary bitwidth and data transfer rates. Which is why nvidia is investing heavily into R&D of chip stacking manufacturing technology. This problem is only going to get worse as GPUs get faster and faster. Within a few years midrange gpus will require this kind of memory bandwidth to prevent a bottleneck.

by most demanding i mean the games that are the hardest to get to full speed on the dolphin emu.

Again, an overclocked i5 3570K (at 4.2 GHz or higher – 4.7 is a good target) and a GTX 650/660/whateverIsuckatGPUs will run everything at full speed.

that is good info to have when i build my own computer one day.
