The only thing I can see that could be changed is go with a 1 8gb stick of ram instead of the 2 4gb this way you can upgrade to 16 relatively easily. If you can squeeze in an ssd even a 120gb that would help significantly with load time of os and applications.
Faster CPU for only 15$ extra, way faster GPU, you can use your Seagate hard drive and install the windows on the SSD in the build. The hard drive will store your games and stuff. I can take it down under 600, but i have to go with weaker CPU and GPU both, and its not worth it. If the price is really to much, we may have to move back to i5 4460 and H81 motherboard.
SSD - windows load for 11sec. HDD - windows load for ... Well you know. You have the HDD... When i say 11sec i mean from pushing the start button until you are ready to use the desktop... Trust me. You want to see the speed difference? Get yourself an SSD... Install your games on the hard drive, get yourself an SSD for the Windows and browsers and what not...
When does the new AMD stuff become available for sale? You might be better off waiting just a bit in order for those cards to come out because the market will change a fair bit in terms of pricing and availability.
Oh yes incredibly so some people like the windows 8 interface I've always found it to tablet like for my purposes and I personally don't use windows 10 mostly run Linux on everything and I am not a huge fan of it constantly wanting to pull data back to Microsoft but in terms of how long it will be supported and the more up to date applications it would probably be the simpler solution.
windows 10 yes, an SSD isnt necessary but is nice. It only affects load times so it wont hurt to not have one while playing a game. Also dont cheap out on an SSD because in a few months it will prove to be a waste of money
Bajesus, please you a comma once in a while. But I beg to differ on the support, Microsoft is not seeing many people using windows 10, which is good, so in the long run their gonna have to change something to get more people on their "new" OS.
