hai friends , i am having 450w powersupply,i decided to buy amd raedon cards,and my choices are 6670,and 6750,plz post your advice

 

[Sunius]

What's your budget? what's the make of your power supply?

 

[refillable]

these 2 are very good cards. But 6750 is better.

 

[de5_Roy]

the 6750 is the more powerful of the two you listed.
what is your budget?
what are the specifications of the pc you're gonna use the gfx card?
which site will you use to buy/choose gfx cards?
how many amperes do your psu's +12v rail have? or psu model. <- important.
a good 450 w psu should be able to support up to radeon hd 6770 and 6850.

my budget is 115 us$,and i found that 6750g minimum power supply of it is 450w but 6670 power supply is 400w

I'd usually say try and move up to a 6870 (122 watts) .... $140ish but AMD lists it as requiring a 500 watter (same for 6790), . ..... a quality 450 should suffice. The 6770 AMD lists as requiring a 450W

my power supply is zebronics 450w and it is marked 18 under +12v,i decided to buy from flipkart.com,my pc specs are core2duo e7400 2.8ghz,4gb ddr2 ram 666mhz,windows 7 ultimate ,motheboard is intel dg31pr, pci-e x16 2.0 slot is provided

zebronics....
upgrade your psu to a quality one from antec/seasonic/enermax. make sure your psu has 80+ rating and lots of amps on its +12v rail. you can support higher end cards with that.

 

[santhosh94x]

it not possible to upgrade psu ,instead you can recommend me the good cards supported by my system within the budget

i didnt want games to run at high settings, i just want it to run at low and medium settings

 

[de5_Roy]

max, radeon hd 6670 with 1 gb gddr5 vram.
with a better psu, up to 6770 or 6850.
edit: the psu should be continuously able to supply power to the gfx card. i suggest a psu upgrade first, then gfx card.
