...NVIDIA GeForce 8800 GT and it's driving some of you mad but what exactly is wrong with the ATI Radeon HD 2600 XT???
First of all, you have to note that many people on here like to spend lots of money to max out their machines whether they actually need it or not. Yes, I realize that many people on this forum are pros and do actually need it, but it can be a little misleading for those of us who don't.
That being said, there are a lot of people like myself who don't need the 8800 and are very happy with their 2600. I have had no problems whatsoever with my 2.8 octo. I am a pro photographer and I don't game, so the 8800 is a waste for me. Personally, I wanted the $200 in my pocket instead of in my machine. I do understand why a lot of people are willing to spend the money, though.
Don't get too caught up in the frenzy. Evaluate what you really need. Reading these forums, I was convinced that I needed at least 8GB of RAM, but for my use, so far I haven't topped 1.3GB of active RAM.
