I have an i3 530, a P7H55V, an Asus 4890 Voltage Tweak Edition, 2GB KVR and 1TB Seagate hdd are running at stock speeds. I am running a fully updated Windows 7 Ultimate and have the latest drivers. The P7H55V bios settings are on default. When I run COD Modern Warfare 2 at 1080p (without AA) the game is showing a little lag. Currently I do not want to overclock anything. Whats the best solution because according to a few people my system shouldn't be showing any lag at these settings.
