I'm looking to buy a 9800pro

I'm looking to buy a 9800pro 128mb and as I was looking at places like newegg and pricewatch, I noticed they were saying "sapphire ati 9800pro" and "powerecolor ati 9800pro". what is the differance and is one type better than the other?

 

I was looking again at newegg, what is the difference between the "Sapphire ATI Radeon 9800PRO atlantis" and the regular "Sapphire ATI Radeon 9800pro"

and one more question is there a big performence change between the 128mb version and the 256mb?

 

Do you see a price rise?

 

This is the one I bought.

Payed a little more for ATI brand.

not sure if it matters, but i heard sapphire is lower quality.

I also heard that core/effective speed is more important than RAM quantity, and that most games/programs do not utilize 256 mb cards.

 

Best Buy has the same card on sale this week for $199.00
