Welcome to the MaxPC forum!
First off, I would say please read the Help Yourself Buy/Build/Quote
sticky thread on this forum as it'll help you out in formatting your build list and help us out in giving you the best possible advice with a faster response. Use the [url] tags to build your list with links to where you are sourcing the said parts so we can see what can be cut or found at a cheaper price; or even replaced with a better value product.
And since you are doing your first build, I'd also suggest reading the Pre-Build/Post reading
help tip post. There's also a lot of other websites and forums that have their own help literature and tutorials on this subject. Anandtech
are just to name a few.
That being said, your list is full of holes that ask more questions than it answers.
1. How many 570's are you using in SLI?
2. Where are you getting your prices from?
3. What other applications do you plan on using besides just gaming?
4. Do you plan on over-clocking or do you have any experience in over-clocking?
5. Are you using any parts from other computers for this build? If so, please list your old pc/parts.
Without going too much into other produces or advising you on a complete build list until the questions are answered, I do have to point a few things out with your build. First off, the ram you choose is a triple channel ddr3 set and will technically not work for your build (yes, I know it could, but it will be forced to go at single channel speeds and blah blah blah), You can find 8gb (2x4gb) ddr3 1600 sets between 40-50 now days, just stick with finding cas 9 or lower and 1.5v or lower. Avoid 1.65v modules as those tend to be OC slower ram unless you actually plan on using nice 1.65 OC modules at the 1866 or higher speeds.
You did not list what model type of EVGA gtx 570 you will be using; even under evga, you are looking at 11 different product numbers all with different speeds, cooler and output connections. A little known fact, if you look at the end of the model number, TR = 2yr warranty, KR = 3yr warranty and AR = lifetime warranty.
For just gaming the i5 2500k will be just as fast the i7 2600k for $100+ cheaper. It's the same chip but without HT. HT doesn't make a difference in current games. Look at the newer Z68 chipsets as they are newer and about the same price as the P67's, they also have the nice SRT ssd cache feature. Don't get the Corsair 800G powersupply, specially at that price. It's a lower quality PSU even though its a good psu and will work for your applications, you can find the newer TX850 v2
for $115AR at newegg, but honestly your PSU choice depends if you plan on going 2 or 3 SLI, same goes with your mobo choice.
As for your hard drive, even my 5 yr old gaming rig had 6x more space than what you plan to get here. And that's back when 500gb drives were $200 a pop! If you want a good speedy drive, then look no further than the Samsung Spinpoint F3 1tb 7200 drive
, its $60 and one of the fastest 7200 drive on the market, even beats the caviar blacks that WD makes. Also for a healthy budget of $2k, I'd seriously look into getting a modern SSD. It's a nice speed boost in opening up applications and files from one.
While the HAF X full tower case is a great case, it's also a very large case and honestly only worth the size if you plan on adding liquid cooling, use a triple or quad SLI/CF setup and/or need lots of space for hard drives. If you want to stay with the full size case, then look at the cheaper NZXT phantom case
, its $125 shipped on newegg right now and is a very nice case, specially at that low price now. It was $160 a week or two ago plus shipping. Also, you can take a look at the HAF 932 or 922 as well, but there's also the Antec 900, the Corsair 600t, Lian Li lancool and a few others in the $100-200 range that will be a nice fit.
