hey brother why dont you get a hd 5670 from flipkart?http://www.flipkart.com/his-amd-ati-radeon-hd-5670-iceq-gpu-1-gb-gddr3-graphics-card/p/itmd2ryn7mjh9pqd?pid=GRCD2RYNWCDCZZQZ&ref=6ec378e7-2d84-4af5-bcc5-fc80222a98d1
it is a 20-25% upgrade from hd 4670 and will play bf3 @ 720p with medium settings
also i advise that you upgrade your processor before you upgrade your gfx card for optimal performance
Thanks bro! It's a good advise.
by the way, Radeon HD 6670 is replacement for 5670 by AMD, I think it is more better and will work fine!
but with the same processor i.e., AMD athlon X2 240 2.81 Ghz how it will work?
