Ok, I wasn't sure if PCI express 2.1 devices would still work in a 2.0 slot, that's good to hear.
I still just don't know if I want to switch to nVidia or stay with ATI.... Obviously by your title and picture you would recommend nVidia lol and that's cool. I'm not really partial to either chipset manufacturer but I usually stick with one brand until I have a bad experience. I don't really like to say it but I guess I'm a product of my environment and almost everybody I've known has always had ATI cards and don't like nVidia, I don't really know why. Most of them have said nVidia is overpriced but it looks to me that the same priced cards from each company have basically the same specs.
Thank you for your suggestions, I think I will probably go with the HD 6850 but I am going to do more side by side comparisons and check out reviews for these many different manufacturers of the cards (XFX, PNY, Sapphire, etc...) before I make a final decision. Normally, in the past, I've just checked out Best Buy for my video cards (lol) so I didn't really know there was such a massive selection to choose from
I normally just see like 3 different levels of cards from either nVidia or ATI and they are usually only either XFX or PNY.
Anyways, thanks again for your input. I didn't catch the HD 6850 when I looked the first time.
