You can't use DDR2 in a DDR3 board, correct. Anywhere a 3800 works, a 6670 and 7770 will work, assuming they physically fit your case. Any cheap cooler that is socket compatible should be fine, you can use socket type as a search criteria on newegg. Assuming you went with the mb combo I posted this would be fine. http://www.newegg.com/Product/Product.aspx?Item=N82E16835103087 I would say that if your more concerned with gaming than say media conversion you might want to spend a few extra bucks and get an intel Core I3/mb/memory. It'll be faster and you will spend ~$200. http://www.newegg.com/Product/Product.aspx?Item=N82E16819115078 $120 http://www.newegg.com/Product/Product.aspx?Item=N82E16813138357 $60 http://www.newegg.com/Product/Product.aspx?Item=N82E16820231423 $20
