First system build needs checking for compatibility

Your build seems pretty good, but I'd go with a 990fx motherboard. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

That is the better SSD, and try looking on amazon for parts, usually cheaper

Hi. What case and RAM do you have? What's your budget and do you mind buying from other websites? It looks like your budget is at least $500. If you plan to go with an AMD processor and motherboard, I recommend changing the rest to these. You don't need a 750W PSU. Although you also don't need a 600W PSU, the CX600 is currently selling for $40 after rebate from Newegg but it doesn't have modular cabling.

i plan on crossfiring in the future when i need to and that card site recommends a 550 watt min so how much do i need for 2? also my case is a cool master case i already have ram that i can reuse. i will get the case next week. shoot i also forgot about cooling fans should i go with coolmaster as well? im gonna want to have at lest 3 cooling fans plus the cpu fan. the cases supports 6 but the board doesnt have the ports for 6 so i may need adapters .

anything else im missing??? please look up the parts to make sure they work anybody thats why the links are there. im a really scared noob   oh and it would be great if the cpu cooler had thermal paste o n it already.

buget is 600 i dont mind going over a little but i would love to say down to 500 for the more inportant cental parts like the cpu psu board case gpu oh and it would be great if the cpu cooler had thermal paste o n it already.

thanks for the info im only gonna crossfire the cards in a few years. i ordered the cx600 with all my parts i might do a few case fans just cause their so cheap. but a cpu cooler is very important though i just might try the stock cooler and see how it handles the heat load.
