Somehow I've ended up with the title configuration, but can't test it yet. I'll be using this desktop mostly for gaming (not 4K) and I expect the Xeon http://ark.intel.com/products/83352/Intel-Xeon-Processor-E5-2620-v3-15M-Cache-2_40-GHz?q=E5-2620v3 to bottleneck the Titan... am I right??

I suppose the Xeon will be running at its turbo speed @ 3.2 Ghz on games, but since I think it's not going to be fast enought to run the Titan at its fullest, I'm thinking to replace the previous Xeon with this new one http://ark.intel.com/products/82764/Intel-Xeon-Processor-E5-1630-v3-10M-Cache-3_70-GHz

My main question is: Will the new Xeon @ 3.8 Ghz be enough for the Titan?

OR

Should I replace the mobo (and the cpu and the ECC ram) to a new one which supports faster cpu like i7?

I know the 2nd option is the most expensive one, but might be worth it if it is to get the most of the Titan and be future proof @ games.

I'd be really greatful if you share your thoughts, tell me if I'm wrong at any point or how to get the most of the Titan.

I would start by DISABLING hyperthreading in the BIOS. You are trying to maximize performance in the cores you have. Don't confuse the OS with the virtual cores, disable them. You have six physical cores which is more than enough.

Thank you for your answer, I will disable hyperthreading

I've been doing some reading on the topic more/less/faster/slower cores (relating to gaming) and the answers are all the same: faster/less cores beats the opposite.

Since I have more/slower cores, will this translate into a drop of performance of games?

I am not a gamer so I can't comment on game performance. I have worked quite a bit in high performance computing. Usually the "HPC" model of a Xeon CPU doesn't have hyperthreading built in. By not having the extra hyperthreading overhead they can get a few extra Mhz out of it. If you tune your application to keep the physical cores busy, having extra logical cores doesn't do anything except slow things down.
