and one more thing can you guys explain to me that DDR3 on motherboard and DDR5 on the graphic card. If it different does it mean the graphic card does not suit the motherboard?
I am from Malaysia and this is all I can afford to buy for now. My bugget in "Malaysia Ringgit" is around "RM4000" if in dollar I think it will be around 1000 - 1500 dollar. I check using google currency lol - https://www.google.com/#q=1%20USD%20to%20MYR
I think I am still under your budget. Your build : cpu+motherboard+gpu= RM1907.
My recommendation : cpu(rm 540=$165)+r9 270x gpu($219)+motherboard($133)=$517 which is RM1692.
So which still leaves you with RM300. So you can buy a nice cpu cooler with it.
I think this cooler should be enough : http://www.newegg.com/Product/Product.aspx?Item=N82E168...
I still think there will be few bucks left, if components in Malaysia are a bit highly priced, which I think they are not, you can easily make it up with it.
