Hi guys, My first thread in this forum. I need some useful advices on my case. I have recently bought this card mentioned in the subject and expected to be an extreme gamer. However, the result made me so disappointed. The card did not run very well on Fear expansion, Overlord and Flight Simulator X... Whatever games i tried, they seem not to be at their best resolution. Even i tried using 1024 x 768 resolution, still very laggy. Overall, the result is not what it is supposed to be for this high end card. So i need some advices on how to solve this case, what should i change to increase performance in my system? Specs given in attachments. This is a brief specs: Microsoft Windows XP SP2 Intel Pentium D 2.8GHZ Gigabyte Geforce 320MB 8800 GTS 1Gb Kingmax RAM single channel P5LD2 - TVM Asus Motherboard (PCI-E), intel 945G chipset 160GB hard drive Power Logic 500W (250W pure power) power supply I read the manual instruction of the card and it said to have minimum 2GB of RAM for better performance. Could this be the problem since i only have 1GB RAM single channel? Also the requirements also said to have a power supply of 400W to be able to run this card. 400W here is pure power or just standard? I have attached the details of my specs in the attachment for anyone who wanna have a clear look at my case. Thank you all and i am hoping to get back some replies ASAP.
