Ok so i found out what my graphics card is.. or at least i'm pretty sure it is.

Ok I just tried it by allocating 3GB of RAM and the settings you said and it still lags pretty hard. Also I heard that 2GB should be perfect for most of the modpacks but thats not the case for my computer

do you know how to check my GPU? That would be great if i could

Ok so I have 6GB of RAM but yet, no matter the amount of RAM I put torwards Attack of the B-Team or any other modpack besides Tekkit Classic I lag. No matter if it's 1,2,3,4, or 5 GB going torwards it, it will lag like crazy! I need help figuring out what i can do to improve most of the modpacks' preformance. I really want to play one good and I know this computer can run it good. Also I have a 64-Bit Operating System and a i5 Core if that helps.
