The RAM you have picked out for your new build will not run on the AMD board; due to AMD boards being dual-channel, not triple-channel RAM configurations. Look for reliable dual-channel RAM packages (2 x 2GB) http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007611%20600006050%20600006066&IsNodeId=1 .
Second; If your primary goal for this computer is for gaming please note that you'll want a case that will give your components the best airflow (the lower the temps, the smoother the gaming). So look for a case that allows for more fans (even water cooling) http://www.newegg.com/Product/Product.aspx?Item=N82E16811129021 .
While we're on the subject of computer cases; I would not recommend anyone building a "Gaming" system to purchase a case that comes with it's own PSU, as most PSU's with these cases are not going to be powerful enough to run the high-end components.
It would be better to find a reliable PSU ( Corsair, Antec, ThermalTake, Seasonic, Silverstone to name a few) that won't break the bank http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007657%20600014022&IsNodeId=1&name=601W%20-%20700W
Third; While NVidia has come out with the awesome "fermi" line of videocards, they tend to really suck up the power, as well as being extremely hot...for about the same money, you could get yourself an AMD 5000 series GPU, say an AMD HD5850 (which runs with lower power consumption and lower temps, both are good things in my books) http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007709%204018%20600030349%20600007320&IsNodeId=1&bop=And&Order=RATING&PageSize=20 .
If you have any questions, we're here to help.
I am in the process of picking out my parts and trying to build my first computer. My budget is around $800-$1000.
So far I have put together this setup:
This system will be mainly used for gaming.
I would want it to run smoothly on the latest games on high settings if not max settings.
Any input or any flaws in this setup will be wonderful!
