I had a compatibility issue with the Radeon with my Intel Mother board and the brand of ram. I had to switch the VC out to Nvidia.
Just giving you the heads up to make sure to google your mother board and VC of choice to see if there are known issues.
Not saying anything bad about any of the brands, it was just my situation.
Which 1 would u say is better, Nvidia or Radeon?
The Radeon went into my friends computer, it works fine. His cpu isn't as good as mine, but it seems like the Radeon pushes a little harder than my 8800 GT (not GTX). However, he has had more technicle issues with it.
It's (the radeon) a power hog. Even though he met the requirements on the box he still needed a better power supply.
It's really hard to compare though because my system is better overall, solid motherboard, intel quad-corem, 4 GB Ram, good 600w PSU.
With power supply issues I would measure the stats carefully, you might be better off with a generation older with out a decent power supply. Other than playing Crysis or Far Cry2 in Very High, it just won't make that much of a difference... spend the extra you save on some games. (There all DX10 anyway.)
I would go with the 9600 GSO, it is second gen DX10 (The 2xxx radeons were not very good DX10)and (depending on the card manufacturer) can be easier on the PSU.
I've had good support from Nvidea and bad from Radeon, but I am just one case. I am not really pushing one or the other, they are all great processors. Make sure you read the reviews on the individual cards.
I am not going on perfromance, more on actual power consumption from my experience (not what the label says) and support.
I am not giving technical advice because I just don't know that much. Try to get others on the internet to admit they're not experts, I dare you. :P
I also wanna double check, make sure you google your motherboard, cpu, and card ahead of time, just in case.)
