$1000 budget build. Need advice!!

Is that 27 inch panel 1080p or 2560x1440? The main component that gives me pause is the gtx650(non ti). You might be able to run the latest games on medium with that at 1080p, but you may want to consider a stronger card. Also noticed you have a closed loop water cooler on a locked down i5 4570(not the 4670K) in an enthusiast z87 motherboard. Maybe that's just the component mix? Don't get me wrong. You should be able to play the latest games fine on that CPU, as well a do some limited overclocking within the turbo multipliers and slight manipulation of the base clock(if you care to take the time). Just water cooling and a z87 motherboard and that CPU don't make a lot of sense to me(again, probably how cyber power does many of their builds).

Edit: I'd choose the corsair c70 for a case. What brand is that 2 TB hard drive?

As said above I would drop the PCI Sound Blaster you have a good audio codec onboard in the RealTek 892 already. If you really want or need a dedicated sound card you could at a later date get a Sound Blaster Z. It would be a much better sound card than any PCI based(Sound Blaster Z is PCI-E) plus removing it from the build now would give you more to put tords a better GPU.

Since you are on a budget I would drop the SSD and put that money into a better GPU. The one you have chosen is really on the low end plus only 1gig ram. SSD's are nice but in the end after the system boots that is where there real advantage ends. And it is something that you can add at a later date.

As far as the OS I would go for Windows 8 it is the future and is really a very good OS. It does not take any time at all to get use to it about five minutes and that is about it.

And then as far as a GPU since you are going for Nvidia i would go for a GTX 660ti(2gig) or better.

Keeping your budget down now by cutting out the SSD and Sound Card and getting a better GPU those things can be added later as you have the funds to do so.

I can't really say much about the CFI Taiji Full-Tower Gaming Case you have chosen as I have never used that brand. However I have not really had any problems with Corsair and have built a few rigs for friends with the Corsair C70 and they are nice Mid Tower cases. For Full Tower I have been using the In Win GRone case lately it also a very good case for Full Tower.

For resolution, you can get a cheap 1080p TN panel(worse view from an angle, less color accuracy than ips but faster response and if you only intend to really look straight on and not share the view or don't do stuff like graphic design or photo editing, the color accuracy won't make that much difference. You may want a faster panel for gaming. 23-24inch for 100 to 150 dollars us for 1080 will give you a tighter pixel density than the same resolution at 27 inches(the larger screen would look a bit blockier, but may be easier to read if that's of any interest to you. You can get a korean 27 in ips panel(maybe with overdrive option) for 300 to 400. 2560x1440 is about 3.7 megapixels where 1080p is about 2.1 megapixels. The more pixels you want to drive, the more powerful graphics card you want(give the amount of quality you can live with like low, med, high, or ultra depending on the game in question). If you were going for 1080p, I'd shoot for at least the gtx650ti boost 2GB on the nvidia side or maybe a HD 7850 2GB on the radeon side(they perform fairly similar at reference speeds with a slight edge to the nvidia card. However, the HD7850 is much more overclock friendly.

About overclocking. It is is way to boost performance at no extra cost to give your system a longer life(unless you overdo it, which could shorten the life of one or more components in your system). There are plenty of guide online in regards to overclocking processors and graphics cards(even some that may apply specifically to your parts).

I'm not too familiar with the c70 except it seems like a decent case and fairly popular. Some hard drive vendors may have a better reputation for long term reliability than others(that may be down to one's personal experience). Many people like western digital drives better than seagate drives, for example.

z77 and other 7x are the older socket 1155 for sandy/ivy bridge processors. z87 and family are for this and other new haswell based processors on socket 1150. So a z77 would not physically fit your currently listed processor.

If you are not overclocking, you might get away with stock intel cooling. Haswell does have a large integrated graphics part which raises the wattage and heat, but if you will mostly use a discrete card that is less of an issue. The cooler master seidon is a lower end closed loop cooler(probably less capable than some air cooling alternatives), but will likely do a better job of keeping your CPU cool than what the intel stock cooler can muster.

There are a variety of Xonar sound cards ranging from around 30-40 bucks to several hundred depending on your specific audiio needs. There are reviews out there for many of the available models. You might even consider an expensive professional grade card from another company, but I somehow gather you are on a budget or just looking at price versus performance in general.

Not quite sure how to answer this. Is your total budget still just 1k? A decent 27 in korean panel would be at least 300 on ebay(one or more models available at retail stateside). You might just want to spring for an i7(both PS4 and XBOX one will support 8 threads).

Then, you need a gpu capable of handling 2560x1440. If you want future proofing and the best quality, you may need to go really big( HD7990 for example). Or 2 gtx 780s. or 2 titans. To run a game like Crysis 3 maxed out at 2x1080p, you need 3 titans. Since you are doing a little less than 2 3rds of that, maybe 2 titans or 2 gtx 780s or a hd7990/ 2 hd7970s(did I just type that twice?). One way to think of 1080p vs "1440p" is the larger one has 33.3% more pixels in both the horizontal and the vertical. If you want to stay in budget(and maybe keep an asus xonar and ssd. The are good for more than just booting the OS), you might consider an inexpensive 23-24 in TN panel with a fast response time and a lesser card(well, some say titan at 1k if you want to play crysis 3 maxed out, or you could go gtx 780, gtx770, or hd7970. I think all those would put you over 1k total(really though, graphics are fairly easy to upgrade, at least if you stick with the same brand so you don't have to delete old drivers and install new ones. Then again, you may find yourself doing that with some frequency anyway.

But yeah, ssd loads all your programs much faster(browsers, games, etc) and will load levels faster as well. Take Battlefield 3 for example. If you load into a map before your enemies, you can get a head start on capping a control point or setting up defenses. That little bit could either be win/lose for your team. or 1st/2nd place for you in a round. I've heard so many people say that after having experienced the overall extra pep an ssd adds to their system, they never want to go back to a HDD for a system drive.

and overclocking doesn't have to be that big a deal. you can get substantial performance gains with a little adjustment(along with doing a little stress testing up front to determine what a lasting overclock will be(ie one that won't burn out your components in months or even a few years. Processors are a bit harder to upgrade(remove cooler, remove thermal material if you intend to reuse that cooler, remove cpu, place new cpu, place new cooler and thermal material, also may require a motherboard bios update while your old cpu and cooler are on before you do all that.

You can get a 27" IPS AOC display 1080p from Best Buy for about $270. I think retail on it is a bit over 300, maybe $320, but it's typically on sale. It's a nice monitor, I've got 3 of them and they're thin bezel, as you're looking for.

As for the rest... for $1000 looking at something like this:
i5 4670k - gaming doesn't necessarily utilize i7 to the max potential, so at this moment, there's no real point. There's very few games that can take advantage of the hyperthreading. Few games are truly CPU intensive, aside from ArmA, to where you'd notice much of a difference anyways. In the system you've listed the GPU will bottleneck before the CPU would.

If you're on a budget, Rosewill Challenger is a good case to start with. On sale you can usually find it for about 40-50 bucks. It has a few fans thrown in, nothing special, but they can get the job done.

Mobo, I'd spend a bit more and maybe get the ASRock Extreme4 or an MSI Z87-G45. A lot of this is going to be personal preference and you'll hae to go with what you like the most.

Memory I'd stick with what you have. Video card I'd go with something like a GTX 760. Best price for performance you're going to find right now. If you bump the budget up just a bit you can fit two of those bad boys into the mix.

The power supply is fine for what you have, but if you ever bump up to two gpus you may want something more efficient and more powerful. Something like a Corsair HX750. Price is about double, but that's one part you don't want to go cheap on.

The RAM will be fine, but it has tall heat spreaders. For the most part those are a gimmick. They look good in the case, but there's not much of a real point to them. They shouldn't be a big deal with your cpu cooler as you should be able to use all DIMMs if you desire at a later date. If you ever switched to a larger air cooler for the CPU you may would lose access to a DIMM with the large heat spreaders on those corsairs.
