yet another pc rig building question

1. i have to say, i prefer nVidia. AMD might be the "better" company. less restrictive, and just less dickish. ^^ but with nVidia cards you will just have less problems. there are more games optimized for nVidia than for AMD.

2. maybe a i5 is the better option for you? the i5-4690 is a pretty good cpu, and cheaper than the i7's. you miss out on hyperthreading, but for most games HT doesn't give you any benefit performancewise (it can even be counterproductive).

3. Win10 is the future. you will have to use it eventually at some point, if you want to play modern games (DX12). if you don't like the start menu - there are always nice, little tools that can give you the start menu you want. i am on Win8.1 right now, and i have a Win7 start menu (and no fucking metro ^^).

My new build:

i5 4460
Gigabyte GTX 750 Ti
8Gb RAM
750W Gaming SilentX PSU

Runs all games without any problem, including GTA V.

1. Pick the GPU that has the best price/performance ratio. Doesn't matter if it's AMD or Nvidia. You should wait for the benchmarks on the new AMD cards before making a purchase decision.
2. There are no budget i7s. You'll have to go with an i3 or a lower end i5. You could try to get a used i7 though.
3. I'd say it's best to stick to Win 7 till most initial issues Win 10 might have have been fixed. If your Win 7 isn't pirated, you can upgrade it to Win 10 within the first year for free.

1. Depends on the Budget. The GTX960 isn't worth the money, in contrast to the equally expensive, but faster R9 280 or R9 280X cards. The R9 290 is also a decent option, if you have more to spend pick the GTX970. AMD is starting to release their R9 3XX cards atm, so that might change the price-structure and make waiting a little more interesting, currently. Edit: For further and better evaluation, all the parts in your current planning are interesting for answering the question to the best possible extent.
2. You don't need an i7 for gaming - The only difference to the i5 CPUs is hyperthreading, which isn't needed or implemented in gaming all that much, because developing games to use hyperthreading is hellishly expensive. SOME games use it, but it's just a fraction.
   Anyhow, the equivalent to an i7 is a Xeon CPU. Xeon E3-1231V3 is the best option to go. From a technical standpoint the same as an i7 CPU, but missing the Intel Graphics and not overclockable. Still, it suits every consumer-chipset-motherboard and saves you some bucks because you don't have to buy a Z97-Board for it (It'd be downright pointless)
3. Stick to windows 7 at the moment. IF you upgrade to windows 10 the license will be tied to the machine, and we don't know the extent of how much parts you can change until you "lose" the license. Also, your old WIndows7 license can't be used anymore as a W7-license. It's a one-way ticket, currently not lucrative, because W10 is still in an early state.

1. If you are locked on inter CPU, I would recommend nVidia, purely for compatibility. I have GTX 750 and works fine, friend has Ti version and he is satisfied with it. I don't follow current trends when I have working PC and not in market for new one.
2. i5 should be enough for gaming, maybe one that is mid-high range if you can afford for future-proofing.
3. Stack with Windows 7, at least for now. All this "you won't be able to play DX12 games" is pure BS, because it will take years for market to have any decent number of games build in that platform. Also, wait for Windows 10 "growing pains" to pass, and major bugs get fixed like service pack 2 and 3 for XP, 7 for Vista and 8.1 for 8.

• Edit: Also, forgot to mention... Try to buy exact models of components that you gonna use. What I mean by this... don't get card with 5 ports if you will use only 1. Same goes for motherboard, excess number of ports will just increase the price of component. I' not saying that you shouldn't have back-up ports, just that you don't need 10 USB ports when you only plug mouse and keyboard in them. Same goes for any other component. Having excess number of slots for RAM is actually good for future-proofing, but don't over reach on that field too.

nvidia, intel i5, windows 8.1 couse 10 unstable

Thanks for all the advice so far guys ^^

Wait a few days, AMD recently announced new GPUs which in a way beats most nvidia products, itll be released like end of june
