i cant buy from amazon,newegg,etc because i live in south america,and the diferences in prices and availability is very great.
i was looking a lot in the market here,i think i will choose the radeon 6870 gpu.
sapphire hd6870 at $1355(equal to 297 dolars) http://www.newh4rd.com/index.php?route=product/product&path=42_55&product_id=413
msi gtx 550 ti at $873 (equal to 191 dolars) http://www.datanex.com.ar/hardware/placas-de-video/nvidia/msi-gtx550-ti-1gb.html
the asus gtx550ti version is 30dolars expensive than msi version.
the best choice is the sapphire hd6870 right?
thanks in advance
