I have only just started trying to play IL2 in the last few days and so far I like it. The plethora of mods is amazing. I am anxious to get the IL2 1956 mod working and get into some Korean war era combat. My Step Father was USMC stationed in Korea, plus I have just always had a fascination with those early jets. Anyway, I am having issues running IL2; frequent GSoD, blank screen and lock up, things like that. I am not really blaming IL2 as it occasionally happens in other games. So I probably have some kind of graphics issue in my system which is an Asus G73 driving a Samsung HD 23" monitor, i7 QM 720 @ 1.6ghz, 8gb DDR3, Radeon HD 5870 with 1gb DDR5, Win 7 Premium Home, TrackIR 5 and Logitech G940. I have an old Dell XPS 710 with XP that I want to upgrade. Due to the age and design of the system, I am limited on upgrades but there are some things I can do. I want to replace the Duo Core CPU with a Core 2 Extreme QX6700, increase the RAM from 1gb to at least 4gb, possibly 8gb if possible, and replace the broken nVidia 8600 GTS with a much more powerful 8800 GTX. I don't have the $$$ for a major upgrade but I can do these upgrades for about $300. I am thinking this should be enough of a system to run sims like IL2...? Any suggestions, comments, snide remarks?
