Help me with my first build

What do you mean by online HD games? Flash games?

Sorry it should have read- I want to play games in high definition, online.

Yes this parts will combine at best with each-other

Okay, I'll assume you mean playing FPS games ...

The parts you picked seem liked they were picked pretty quickly

I think this would be better:

Cpu: i5-3570k (ivy) - no need for i7, it only makes a difference when doing thiings like video editing and animation
Cooler: 212 Evo
Mobo: Asus Z77 Sabertooth (don't get matx, I don't understand why you picked that with your budget and all. look this one up. someone will probably suggest something else, but this board is stylish and performs well.
GPU: gtx 680
Memory: get the low profile version of those vengeance ones you picked the 212 evo gets in the way i think
PSU: I've heard people recommend the corsair hx750w. i don't know much about it though, but with your budget, seasonic x850 all the way.
Case: I'd get a Lian-Li case and Silverstone, but those are just my preferences, you may get what you want.

229.99: CPU
30.99: Cooler
229.99: Mobo
469.99: GPU
39.99: RAM
169.99: PSU

~ Newegg prices. All for a grand total of 1171. you can even upgrade to the gtx 690, or get water cooling and a better case than the HAf 932

if its just for games id do what someguy543 said, but also there's no need at all for 16gb of ram get 8 games rarely use more than 4. also i think a 680 is overkill get a 670 it will play bf3 ultra above 60 fps no problem anything over that wouldn't matter because your monitor you picked isn't a 120hz but if your really up to pay for the 680 go for it

I didn't bother checking his monitor. since you have so much money anyway, you could get one of asus's 144hz monitors. its not that much different from 120hz though.

you don't need the death adder, id get something cheaper and spend that money on water cooling.

alltho the deathadder is very nice i have one best mouse ive ever used

Ok so after taking what everyone said into consideration this is what ive got

CPU: i5-3570 (is the i7 3770 more future proof?)
MB: ASUS sabertooth Z77 (will this MB work with all the componets?)
GPU: EVGA GeForce GTX 680
PSU: Corsair HX750 ( I assume this PSU will power everything and be pretty stable)
CPU Cooler: cooler master 212 EVO
HDD: Western digital 1TB 7200 RPM
SSD: OCZ Vertex 3 120GB
RAM: Corsair Vengence 8GB (2x4GB) low profile
Optical: Pioneer 12x BD-R
Case: Cooler Master 932 advanced (I like the look of this case, and I hear it is very cool)

Periphials:
KB: logitech G110
Mouse: RAZER deathadder
Monitor: ASUS VE278Q 27" 120hz (this monitor should be able to take advantage of the 680's capabilities)

So is this any better? Is there a better build that I should be looking at? As for the water cooling, I will look at upgrading to that later.

that looks much better to me for being a gaming rig,and that psu will be very stable with those parts it has room to spare
