Hey this is the first time i'm building my own desktop. I've chosen all the components but I would feel better if I could get someone who has done this before to tell me if all my components should be fine together. I did some research on my own and have chosen the current parts based on my understanding of pc hardware.

Well. what's your budget like? That's a huge factor

Budget is $1200-$1500. I'm trying to keep it as low as possible while still being able to perform how I want it to.

For RAM with that particular mobo, you're looking for DDR3 2200, 2000 or 1800Mhz RAM.

You might want to buy a higher watt power supply in case you want to crossfire in the future.
Not sure what XFX's reputation is with power supplies is.
Sporting a Corsair PSU here.

I also go Western Digital for HDDs

DDR3 2200 RAM looks kinda expensive but you can get 4 gigs for now for $99 and add 4 later if ya want...
Some choices at NewEgg.com below.

" @Azteck: Weird that it doesn't list comatibility with 1155 on that review but I'm using 1155 chipset too and it fits fine. That fan you linked should be fine though. "

1156 coolers are said to be compatible with 1155. That review was done a year before the 1155 chipset came out. Coolers which came out before 1155 wont be listed as compatible. However, If its 1156 cooler it will work for 1155. They are the same except 1155 chips were changed so they can't be installed into 1156 socket. For coolers it doesn't matter, for them its 1155=1156. This it what I understand from researching anyways...

Edit: As for the build I would go with a power supply by Corsair, Seasonic, or Antec. For HDD Western Digital Caviar Black. Corsair, Kingston, Crucial, or G-Skill ram. Don't skimp on the power supply.

Umm, stay away from the storm scout, it won't fit longer videocards. Not really confident about the hitachi hardrive either, you might want to go with a better brand as others stated. Memory, download from the asus site a memory compatbility list, you will know what works for sure. Like others said, not sure about xfx's quality in psu. About the cpu cooler, you can get away with stock cooling with the sandybridge, but buy whatever you want.

I would check out  http://www.ibuypower.com/ They are have a sale on Friday the 13th. I  bought my last PC from them and it ran well.

" @Vinnylegs:@HitmanAgent47: This XFX PSU is a rebadged Seasonic so it should be pretty solid. "

Today's Black Edition 750W ( P1-750B-CAG9) is produced in conjunction with none other than Seasonic, who was responsible for helping Corsair launch its first highly successful line of power supplies and XFX's own Black Edition 850W.

DId you already order everything?

I have the storm scout case, it is really short on space for larger video cards, but the storm sniper case looks to be significantly larger and should have plenty of room.

" @CaLe: That particular ram went back it stock so I decided to get it. Thanks.

Also, I dropped the HD in favor of this one:  http://www.newegg.com/Product/Product.aspx?Item=N82E16822148506

I'm pretty much set except for the monitor. I know that a monitor that fits this build usually costs around $400-$500 but does anyone know of any good monitors for around $300?

 A larger sector size results in higher net capacities because it decreases the amount of ECC data and the inter-sector margins. WD says that going from 512 bytes to 4KB sector size results in a net capacity increase of 7 to 11 percent. ECC efficiency could also increase, as one long ECC code requires less computation than multiple small chunks.

Sorry, I don't have enough experience with 2tb hardrives and my advice about problems applies mostly to green drives. Since wd has bad reviews, maybe the hitachi or seagate one is okay for 2tb. I never ran those brands before, I usually give the same advice, but I mostly only recommend SSD drives or 1tb hardrives, not 2tb.

 But for the monitor, maybe you should go with an asus led instead. It just takes a bit of calibration to deal with the high contrast. I can help the op with this, I have helped ppl with calibration before. This monitor is also 27" and it's an led made by the same company as you posted. I figure if you were willing to spend this much, that would be a good choice. It's bigger than most monitors too and the reviews seems to be overall positive.

edit: found a graph on failure rates or returned hardrive, which probally means failure. My advice is true of the 1tb hardrives, but things are different with 2tb, WD black isn't that reliable for that. Then maybe you can get whatever you want, stay away from WD black for 2tb drives, but for 1tb, get WD. At least my hitachi deskstar advice is accurate, they are the second highest returned hardrive for the 2tb version. WD black is the second least returned hardrive for the 1tb hardrives. Then again maybe ppl didn't return maxtor because it's not a popular brand.
