Do not listen to these above posters, if You blow the money for a 7000 series Radeon I will shoot You in the foot. I'm about to upgrade from the above linked card to a 6850, A SIXTY EIGHT FIFTY to triple my GPU processing power from the Nvidia 545.
I'm telling You right now that I use that 545 and will submit Screenshots if you do not believe me, and I play Warcraft not only on Ultra, but I play it on Ultra at 1920x1080 with the Graphics GPI macro's the macro's that tell the game engine to go beyond Ultra. I raid 25 man's, Dragon Soul Hard Mode with my guild and never come off 60 FPS while sitting at roughly 55-65 degrees C under full load.
Top this off with the cherry on top? Sure. I play Crysis 2 at 16xQAA and Mass Effect 3 at 32xAA and Tera Online at Ultra settings, everything on Ultra Crysis/ME, and this card handles it, little choppy on the 25-35 FPS with Crysis 2 under AA conditions, turn it off and it runs at 45 FPS solidly.
I'm telling You telling You telling You, as a gamer who built a rig to play WoW on Ultra, I use that GPU and have no problem with it what so ever. DO NOT BUY a $350 7000 series RADEON LIKE THESE TOOLS ARE TELLING YOU TO. Spend the $100 on the 545, I spent $70 on mine at CompUSA. Build it yourself, do it.
Another reason I'm being this adamant here is this. The 545 has 1.5gb of Memory on it, these above cards are all at 1GB. I'm telling You that I see my Memory get used, and under game load, idle above 70% meaning it's using over 1GB. I've seen people with 580 GTX's with 1GB on memory have low FPS and screen tearing, they replace the 580 with a 2GB 580, same GPU, and it all goes away. That memory matters immensely. Also, I looked at the costs of their 7700 cards and I flipped for a second thinking they were talking about the 78/7900's so it wasn't as bad as I thought, I assumed they were saying buy a $350 card to Play Wow. Still though, You can get this 545 for $70 if You shop around like I did at CompUSA, and it will do everything.
