Ok, so I finally got a 9800GTX+, but it isn't as good as I thought it would be, I can't even play Assassins Creed on medium without lag, while I've seen 8800GT's play it on high without lag, and I can barely play Crysis on mainstream/gamer. Also, it says that it is 512MB, but when I run GTA IV, the memory ristriction say like 450MB (I can't remember). My CPU is an AMD Phenom 9500 quad core @ 2.2GHZ default (I overclocked it to like 2.5GHz. I have 6GB RAM. And a PNY 9800GTX+. Somebody told me that my CPU is bottlenecking my GPU, but I doubt it. Is my graphics card broken? Because it is pretty ***. I have a 550W power supply which is enough. I'm really dissapointed because I bought the 9800GTX+ and a 550W power supply for over $350. Please help me I don't know what is wrong with it. Thanks in advance.
