What graphic card for 1080p gaming?

[Abe504]

I'm having a tough time figuring out what graphic card to choose.

I plan on playing at 1920X1080p resolution

These were a couple of graphics cards i was looking at but don't really know which one is the best for my needs

Gtx 460 SSC+ _ Main question i had with this card was does it clock the same speeds as the 560 TI?

Radeon 6870

or

Gtx 560 Ti but a used version, would it be safe to buy one used from amazon or just buy a new one?

Thanks for advice

Once in the $200 range, I'd look for a 6950(1gb) for about the same cost; below that budget, the GTX460(1gb) offers good performance for $120-ish on sale..
