6770/550 Ti/6850 ?

[diablopiyush]

Hey Guys, i had built a pc late november in 2011 with specs:-

Intel 2600k
ASUS P8Z68-V (only for lucid virtu)
Cooler Master eXtreme Power Plus 500W
500GB Seagate HDD
2x4GB 1600Mhz DDR3 Ram
22" 1366x768 LCD Philips (not FullHD)

but i left out on graphics, cos of a student's budget constraints, and i'm not much of a gamer either. Now that i have saved money
for a graphics card, please suggest me which one i should go with 6770/550Ti/6850.
Please note that im a casual gamer,and i wont be gaming at resolutions more than 1366x768,so will 6850 give me playable FPS on heavy games maxed out ?
Also , once a month i might hook it up with my Bravia 42" Full HD LED, how would these cards perform?

The 6850 is best option.

6850 will perform better than the other cards , but regarding the part that u want to play games MAXED OUT don't know if it will be enough ... if u can go for a 6870 , there's a "Small" price difference but u'll get much better result with it

i haven't read good things about cm's extreme power plus psus. you could look into getting a better psu like corsair builder series cx 500 v2 or antec neo eco 520w or seasonic s12 ii 520w.
with a psu upgrade, you'll be open to using powerful gfx cards in the pc.
with your current psu: radeon hd 6670 1 gb gddr5. it should be able to handle casual gaming at 1366x768. you could also look into radeon hd 7750 (new 28 nm gfx card that doesn't require extra pcie power supply).

yes de5_roy is right but if u dont think to overclock your gpu and cpu then that psu will be ok it can handle single hd 6850 and for hd 7750 it will perform like a hd 6770 only thing is that it uses less power and gives good performance but in all of that hd 6850 will be the best choice.
