Which ATI card to buy?

[Conficio]

Hi there,
I'm confused by the array of ATI Radeon cards on the market and their differences.

I'm mostly a desktop user and don't do gaiming, (at best a simulation game). I want to pair in i7 860 with a card that would support potentially a dual screen. I have settled for an ATI 4850 as it seems to be readily available and well supported. However, I don't know why I would prefer an XFX over a Gigabte card. They seem to have the very same specs.

Just in case I'd prefer a quieter card.

Is there some buying guide somewhere, that I have not found?

Also, is there a reason I'd need 1 GB or is 512 just enough?

Wait a little for the hd5670.

XFX = double lifetime warranty, Gigabyte = 3 years

Yeah specs are the same because they are based on the same chip (or even the same reference design). Go with the one with better warranty or bundled accessories. If you don't want to wait, grab a 5750.
