First Gaming Build $800-1000

Thanks for the input everyone, when it comes to the 280 and the 280x what are the difference? I remember reading somewhere that the only difference between the 270 and 270x was that the 270x was built as a pre OC oem part soe the 270 would be a better option because you would be able to OC it better than the 270x. Is this the same for the 280's? Also what wattage PSU should i get for this build if I plan to OC?

And a friend of mine who build his setup with AMD said he kind of regrets going with it right now because he's big into emulating/emulation games on the PC and that AMD falls off kind of hard for them and he wish he would of gotten an Intel. How true is this? I'd like to run emulations but im not super big on them just a few here and there, so would i notice that big of a difference between going AMD and Intel?

As to what games i'll be playing I'm not really sure, I used to be big on PC gaming but for the past 2 or 3 years I've had to deal with and old POS HP laptop that is currently falling apart. Mostly I play league of legends (and I know this build is more than enough for league) right now because I can still run it decently on my laptop. But once I finish the build I plan to get back into PC gaming. I usually enjoy MMO's, FPS, and RPG type games so any suggestions would be great because I've really lost track of the good games in the past few years.

What does the MX 100 have over the Samsung, I know alot of people prefer the Samsung series SSD's thats why I went with that one.

Anything I could save some money on? I know I can probably pick a different brand of RAM and save $10-20 for the same latency/ddr3, and would it be worth it later on to Crossfire another graphics card in or just completely upgrade the GPU down the line?

Lastly how is this build for overclocking I did a little reading here and there as to what parts are good and bad when it comes to that but I have no real experience with it, my friend was going to teach me how but he's been busy and hasn't seen my parts list yet.

Sorry for all the questions, trying to learn because im seriously considering going back to school for my Computer Engineering or Computer Science degree.

So it would be better to just spend the extra $50 to get this http://www.newegg.com/Product/Product.aspx?Item=N82E16814121867 instead of this http://www.newegg.com/Product/Product.aspx?Item=N82E16814150706 ? Im probably gonna drop the SSD for now and just get it later on down the line.

Edit:I posted the links above backwards by the way the XFX was meant to be first xP, meant to be would it be worth it to spend the extra $50 on the XFX 280x instead of the Asus 280.

Any suggestions on a good but cheap power supply I know a user posted a 550w Earlier but the one thing I dont like about Pcpartpicker is that they include the mail in rebates in the price you pay.
Would like to avoid mail in's if possible knowing me i would for get to do them plus im trying to keep what I pay upfront under $1000 not what I spend after rebates xP

Ok so this is my build now, I switched out the case because the previous one didn't have any usb 3.0's while my Mobo did, and switched from the corsair Vengence to the Crucial Balistix Sport to save a few extra $, and on my PSU how is the EVGA 600B 600w 80+ Bronze any better options? I know you recommended the SuperNOVA 750g2 but how does this one compare?

I found this complete build minus the GPU for $756.55 at my local micro center. Im probably going to order the GPU online at Newegg and pick everything else up in store, because they only carry 2 280X GPU's the XFX and the MSI. The MSI they have at $310 and the XFX is $340.

Here is the XFX they have.

and this is the MSI
http://www.microcenter.com/product/423128/AMD_Radeon_R9_280X_Gaming_3G_3072MB_PCIe_x16_30_Video_Card

which one of those would you suggest? I think that XFX is slightly different than the one posted earlier but not entirely sure

With the XFX the total is 1137.59. With the MSI its 1105.51 with Tax included picking up in-store at the local Micro Center. (It will be slightly cheaper than this I'm micro city usually has instore discounts when buying things together). So for the price how is the build.

Ok thanks for the advice everyone I really appreciate it. How was the PSU that I picked by the way? Would there be a better alternative for that price?
If not then I should be able to pick up the parts later this week hopefully and start my build.

This one had good reviews thats why I picked it in the first place. How does the supernova 750B compare to the G2? They have it for $5 more than the one I have picked out at the moment and am probably gonna switch over since its $5 for an extra 150 Watts

So I plan on buying the parts this weekend, this is the mostly final build I have right now.

I couldnt find the power supply I have picked out on pcpartpicker so here is the direct link.

http://www.microcenter.com/single_product_results.phtml?product_id=0433775

So how is this build, I picked out a much better power supply. Atleast according to the Power Supply Tier list posted here.

Also since I plan on Overclocking, with this build would it be better to save the extra $40 and go with the FX 8320 or stay with the 8350, since they are the same chip but the 8350 just has a higher base clock speed. From some things I've read with a decent PSU and Cooling the 8320 can pretty much match the 8350 in overclocking for a bit more power from the PSU.

I found a bundle for the i5 4690k and the MSI z297 Gaming 5, with those the build runs me 1242.59, a little over budget but I wouldnt mind spending it if its worth the price. Whats your opinion? Its $1172.23 vs $1242.59.
