pcie 2.0 is backwards compatible so yes it will work
why are you going for a two gen old card sir?
you should look into 7750
Are you sure that it will work well and most importantly fit since I saw others saying that the card wont work at full speed on v1? I chose this card as my budget is only around 4000 rupees(90 USD) and I want to play games like bf3, mw3 etc. on atleast mid settings. Is my ram enough for low to mid settings as I cannot upgrade my ram?
Also is this card preferable since it is the only one in my budget?http://www.flipkart.com/powercolor-amd-ati-radeon-hd5670-1-gb-ddr3-graphics-card/p/itmd5ynejajvnugy?pid=GRCD5YNDPUNSBGRK&_l=eMkFvRRNzht07TRKwH82mg--&_r=4dbc3hLgeiJvVtnjJcXBfQ--&ref=dd392ac4-d573-41b3-bc59-7aa50f392c64
