Hi have just built a new righ with a radeon 5770. Specs are as follows: 2GB corsair ram 133mhz phenom x2 550@ 3.1 500gb wd hdd as rock mobo artic cool 500w psu. I am really pleased with my system overall and I love it. One tiny thing that is niggling me and I can't figure out is when i'm games, it seems that when its rendering something new there is a literally 1/2 second freeze and it only happens once like first loading a map. I know its not much but its niggling me. Example: Last night i was playing killing floor. Once you fight through a wave of zombies you get 1min to get to a shop and stock up on weapons ammo etc. When the timer runs out a bigger wave a zombies comes your way. I was looking down a corridor and a horde came round the corner towards me. As it did there was a freeze and then for the rest of the game it was fine. Its like it needs to render it or something. I've benched on furmark everything is fine and stable and the fps is a stead 70 on killing floor and 23 on extreme burn mode on furmark so I know for a fact that its not drivers, or fps issues or lag issues on a server pLEASE HELP thanks
