Come on guys, try to at least be constructive, you've got someone here who would love to change his opinion on AMD performance in WoW but you're taking the forum troll route and providing no proof. Please read a little before posting personal claims or claims based solely on community opinion.
Ever notice the Nvidia banners plastered all over Blizzcon? When I said WoW is optimized with Nvidia hardware, I wasn't speaking of some conspiracy based off a random Tom's Hardware article, it's a program called "The Way It’s Meant to Be Played" and it's common practice in the video game industry.
Here's the press release announcing Nvidia and Blizzard's partnership for WoW...
NVIDIA and Blizzard Entertainment Team Up for World of Warcraft
"Blizzard has optimized the game for NVIDIA hardware and is working with NVIDIA to ensure the game plays well across a broad lineup of GPUs" - Bill Rehbock, general manager of content development at NVIDIA
Also, nothing I've said up until this point has suggested that Nvidia is any better than AMD in general, this is not an Nvidia vs. AMD thread. Nvidia is 3-6 months behind AMD in every way and no matter which way you cut it, that puts them at a disadvantage. AMD is absolutely killing it right now in both price and performance, but when it comes to WoW, the fact is Nvidia has the upper hand.
Please, for the love of all that is holy, give me some hard numbers to work with if you still think I'm blowing smoke. What a welcoming forum community...
