What type of ATi Card To Get?

Hi, I'm looking to purchase a 1Gb 4870 ATi PCI-E card for my system, and have found that brand new they are very expensive from the computer places but are at least $100 cheaper on Ebay and they are brand new. Here are the cards I found on Ebay:

HIS ATI Radeon HD4870 1GB 1024MB 256Bit DDR5 HD 4870
HIS ATI 4870 1GB DDR5 Full HD Graphics Card Upgrade

I'd like to know if there ahve been any problems with these and what the best one would be to have.

My requirements are not to have a card that is already overclocked, and i won't be overclocking it either.

Why on Earth Ebay? What kind of customer service are you going to get if you need to return it? Most manufacturers wont even accept a RMA if the product wasn't bought at a certified dealer.

Any 4870 1gb is going to perform within 1-3% of another, given they are the same clock speed. Make sure you get one that blows heat out the back of the case.

The cheapest ones dont.
