Hi all, First time post here and i have some questions re my slow running pc, mainly in gaming. Firstly current specs: (built it 5yrs ago, so it's 'aged' abit) Intel E6700 @ 3700ghz (watercooled) Asus 9800GTX+ (stock) Asus P5G41T-M LX3 G Skill Sniper 1333mhz 8gb Windows 7 64bit Now the problem i'm having is that my previous motherboard died (Asus P5N32-E SLI) and i replaced it with the above board. When i did this, i had to change from DDR2 to DDR3 (DDR2 was G Skill 1066mhz 4gb). Pre board change i could run MW3 fairly well, also MW2 extremely well but since the change of MB & RAM i can't run either, frames are about 30fps average, which is unplayable What are your thoughts on the problem? Motherboard bottleneck? Any suggestions on how to find the route of the problem?
