I would like to upgrade my current setup to improve my gaming experience. I also use the computer for some data analysis but that software I believe can only use a single core and I'm not sure about HT.
I'm thinking of buying the following:
cpu: i7 2700k 3.5Ghz (or i7 3770k 3.5 Ghz)
mobo: ASUS MAXIMUS V GENE
cooler: Arctic Freezer i30
ram: DDR3 2x8192MB CMZ16GX3M2A1600C9 Vengeance (9-9-9-24 1.5V)
+ an SSD drive for the system and the most used games (2 or 3)
For now, I'll be using my current GPU and plan to buy the top-end (single) NVidia at the end of the year.
I know that 2700k natively supports only RAM up to 1333 MHz but I read it works nicely with 1600 MHz regardless. I've read extensively the discussion about 2700k vs 3770k and I tend to go with 2700k to save 40 euros and less heat and more OC.
I would welcome any suggestions for a different/better mobo (up to ~150 euros), a better air cooler (a few degrees improvement) and/or other RAM options (I chose this one for the 1.5V which I read is a good option for OC).
i'm not sure what websites you can buy from but i would look at something like this. really no reason to get sandy bridge over ivy. especially if you are buying a z77 board. you said you don't need hyperthreading if that's the case get the 3570k. if you will use hyperthreading get the 3770k. ivy bridge is faster clock for clock so it makes up for any extra OC you can get out of the sandy bridge cpu.
i would get a cheaper motherboard unless there is some feature you need on the asus. you could also get a 128GB ssd for cheaper. get 1600 memory there is almost no price difference from 1333.
