I was looking at a 6850, a 7770, 550ti, or a 460.
Which would be a better choice?
I have ~120$ budget.
Has to be on Newegg, or any popular site though
None of the Above? Go with a HD 6870 you can find one around that price range if you loo.Ok
*** If you can't find a cheap enough 6870 where your at, then I'd probably go with the 6850 personally although the HD7770 is newer and might have some minor new features the 6850 seems to beat it in most gaming benchmarks (by 1 - 5 frames) ***
A little higher than $120, but the 6850 benchmarks higher than the 7770 in most games. For the price, I highly recommend it
