1 - That's fair enough.
2 - That's fair enough too.
3 - The difference between an i7 and i5 is that the i7 has a technology called HT (Hyper-Threading). It takes the number of cores, 4 in the
this and doubled it to 8. Meaning you've got 4 physical and 4 virtual cores. This makes the i7 good for when dealing with heavily threaded
applications and for editing software. The i7 does perform better, but the reason it's so often ill-advised, is that you'll pay several hundred
dollars more and get very marginal returns. This is why the i5 is the sweetspot, as it already has 4 cores. Games can run fine on at least
dual-core setups, but quad-core will become increasingly necessary. So it's in the interest of saving money, because afterall, if yo're into
games that much anyway, what's usually more important? The CPU or GPU? Usually it's the GPU. Thus you can get the optimum
performance for the money and then sink the money you would've used on an i7, into a better GPU, thus netting a better result for the
same money. You can get extreme edition i7s where the only difference between them and their lower 3570K i7s, is that they have a
300Mhz clock and a few more MB L3 or L2 cache. But they can cost up to a thousand $ or something crazy like that. For what? A few FPS
difference? Now that's diminishing returns if I ever saw it, using that much money and not seeing a SUBSTANTIAL performance boost.
In your case, since you're into editing and such, I wouldn't be too averse to you getting an i7.
4 - Same deal as before. Titan, massive cost, low-returns. That's in fact what the GTX 780 set out to counter. It provides much of the same
power of the Titan, as it's still using a GK110 GPU, but with a little less of things like CUDA cores (proprietary Nvidia tech). BUT it also does
so at a much cheaper price point. There's also cheaper cards in SLI which beat the Titan. So I think it's a bad investment. My policy is get
what you need (and you won't need a Titan/SLI GTX 780) unless perhaps you're running several monitors. You're better off getting a GTX
770 or 780 now and then upgrading again when you feel you need it. Thus you'll save money and the money saved, can be used to
incrementally upgrade your rig, rather than splash once and then never again for a long time.
5 - Have fun.
6 - Something Corsair perhaps, at 650W-700W, depending on the rest of your setup.
7 - Be my guest and go with a 512GB SSD. But as I said, it's hugely expensive and a waste of money by most peoples standards. You're
welcome to do what you feel is best however. I prefer 1TB to 1.5TB and 128GB or 256GB tops. If I need more storage, I add more HDDs,
instead of increasing the size of individual HDDs. Adds more redundancy in case of failures and so forth. Sort of like not putting all your eggs
in one basket.
8 - Mostly it's the price alone really and the thought that you could be spending the cash on things more worthwhile. Up to you .
9 - Well since you're editing too, 16GB will feel nice. 8GB is the "recommended" while 4GB is the minimum. At least for things like PhotoShop
I believe. Very rarely will you ever need 32GB or more. Check my signature.
10 - Asus is good too.
11 - Fair enough. It's personal preference.
By the way if you're using 3D modelling software and it's stuff like 3ds Max, you'll usually need a Pro edition of Windows I believe.
You're welcome mate.
